factors assessment of a repair material for brick masonry loaded cracks using Magnesium Phosphate cement
Construction and Building Materials, 2020Co-Authors: Ban Jin, Longzhu Chen, Bing ChenAbstract:Abstract Cracking of old brick-concrete structures is a serious problem in Shanghai. It is necessary to use quick, high-strength materials to repair load cracks. In this paper, a kind of Magnesium Phosphate cement (MPC) mortar was developed and selected as the bonding material for brick masonry-loaded cracks. Factors such as the water-binder ratio, sand-binder ratio and borax content that affect the properties of the MPC mortar were studied, and a suitable mixture proportion was chosen for repairing fractured bricks based on the results. Indoor experiments were conducted for assessing the mechanical properties and repair performance for repairing fractured bricks by two kinds of bonding methods. The results show that the MPC mortar has good performance in quick repair projects because of its short setting time and early strength. Using MPC mortar as a bonding material for brick masonry loaded cracks not only achieved the desired bonding effect, but also significantly improved the speed of the repair.

microstructural characterization of basalt fiber reinforced Magnesium Phosphate cement supplemented by silica fume
Construction and Building Materials, 2020Co-Authors: Muhammad Riaz Ahmad, Bing ChenAbstract:Abstract This research studied the high-temperature resistance and water resistance of Magnesium Phosphate cement mortar containing different proportions of basalt fiber and silica fume. The improvement mechanism was discussed with several microstructural investigation techniques. It was noticed that increase in the content of silica fume and basalt fiber improved the water and high-temperature resistance of mortar composites. Performance of MPC mortar composite containing 10% silica and 0.5% basalt fiber was superior to other composites showing the water and temperature resistance coefficient of 1.16 and 0.5 respectively. Mass loss results of samples exposed to elevated temperature and those calculated from the thermogravimetric analysis were in similar range of 10 to 12%. Results from mercury intrusion porosimeter indicated that porosity of mortar composites was progressively decreased from 27.4% to 21.05% by increasing the contents of silica fume and basalt fiber. Finally, microstructural analysis of paste samples revealed that additional hydration products were formed beside the main reaction product struvite which supported the enhanced performance of MPC composites due to inclusion of silica fume and basalt fiber.

mechanical strength and flexural parameters analysis of micro steel polyvinyl and basalt fibre reinforced Magnesium Phosphate cement mortars
Construction and Building Materials, 2020Co-Authors: Aminul M Haque, Muhammad Riaz Ahmad, Bing Chen, Syed Farasat Ali ShahAbstract:Abstract Magnesium Phosphate cement composites exhibits higher compressive strength with high brittleness in nature that minimizes the scope of this material for flexural ductility performance. The study targeted to enhance the flexural qualities along with compressive strength of MPC compound through adding the three different fibres such as micro-steel fibre, polyvinyl alcohol fibre and basalt fibre. Inclusion of each fibre was followed a consecutive dosages system such as 0.6%, 0.8%, 1% and 1.2% of the gross mass of binders and aggregate. The compressive strength, three point flexural strength, four point flexural strength and splitting tensile strength tests were considered to explore the flexural characteristics and modulus of elasticity of the prepared fibre reinforced Magnesium Phosphate cement mortars with the passage of age. The experimental results pointed out the improvement about 20% to 43%, 15% to 25% and 50−72% in the TPFS, FPFS and STS than control specimens at 28d, whereas only around 5% to 10% progresses were noticed in CS for the inclusion of fibres from 0.6% to 1% in FRMPC combinations. In addition, the outcomes of flexural parameters analysis from load-displacement curves exposed the well development for mixing of 0.8−1% MSF and 0.8% PVAF and BF in the representative MPC compositions that displayed the deflection hardening and deflection softening behavior suitably. Moreover, the L-D curves of TPFS showed the advanced MOE because of less stress distribution intensity in whole cubical samples with low deformations in comparison to other two flexural tests. The study also suggested some power equation based empirical expressions for predicting the strength properties at early ages and correlation equations for flexural tests including MOE in relation to CS results. The analytical findings and recommended correlation equations might be applied in the practical applications of FRMPC related aspects.

a comprehensive study of basalt fiber reinforced Magnesium Phosphate cement incorporating ultrafine fly ash
Composites Part B-engineering, 2019Co-Authors: Muhammad Riaz Ahmad, Bing Chen, Jiang YuAbstract:Abstract This study investigated the influence of ultrafine fly ash (FA) on the mechanical properties, elevated temperature resistance and water stability of basalt fiber reinforced Magnesium Phosphate cement, and synergy mechanism was examined with the help of X-ray diffraction (XRD), thermogravimetric analysis (TGA), mercury intrusion porosimeter (MIP) and scanning electron microscopy energy dispersive spectroscopy (SEM/SEM-EDS) analysis techniques. Experimental results showed that incorporation of FA improved the mechanical properties, temperature resistance and water stability of MPC composites. TGA results exhibited that the mass loss of MPC composites was gradually reduced by increasing the percentage of FA. MIP analysis showed that cumulative pore volume, volume percentage of large pores and mean pore diameter of were decreased with the addition of FA. XRD and SEM-EDS analysis of MPC composites revealed the formation of secondary reaction products, that could be possibly responsible for the superior properties of FA/MPC composites. Importantly, the results of all characterization techniques corroborated with the mechanical results of MPC composites.

properties of Magnesium Phosphate cement containing steel slag powder
Construction and Building Materials, 2019Co-Authors: Yu Jiang, Muhammad Riaz Ahmad, Ing CheAbstract:Abstract Magnesium Phosphate cement (MPC) belongs to the family of chemically bonded Phosphate ceramics and exhibits certain outstanding qualities. The current study investigated the effects of steel slag powder (SSP) on the properties of MPC mortar. MPC mortar specimens with different content of SSP were prepared and their workability, mechanical properties and water resistance were tested. Moreover, microstructure and phase composition of MPC paste were examined by Scanning Electronic Microscopic (SEM) and X-ray diffraction (XRD) techniques. It was found that the incorporation of SSP can promote early hydration rate. A significant improvement in the later stage mechanical strength was observed but early strength was reduced. Water resistance of MPC mortar specimens was improved by increasing the percentage of SSP from 0% to 30%. Finally, XRD and SEM analysis of MPC pastes corroborated with the mechanical strength results and confirmed the formation of secondary reaction products along with the main hydration products struvite and residual magnesia.

Journal of Colloid and Interface Science, 2016Co-Authors: Yingjie Zhu, Tuanwei Sun, Feng ChenAbstract:Magnesium Phosphate materials have aroused interest of researchers in recent years and are promising for biomedical applications due to their good biocompatibility and biodegradability. In this work, we report the microwave-hydrothermal rapid synthesis of Magnesium Phosphate pentahydrate nanosheets (MPHSs) using biocompatible creatine Phosphate as an organic phosphorus source. This method is facile, rapid, surfactant-free and environmentally friendly. The as-prepared MPHSs have an obvious pH-dependent dissolution performance which can be used as an ideal pH-responsive nanocarrier for drug and gene delivery. Moreover, the MPHSs have a good cytocompatibility and a high ability to promote osteoblast MC-3T3 adhesion and spreading, as well as a relatively high protein adsorption ability using hemoglobin (Hb) as a model protein. Thus, the MPHSs are promising for the applications in biomedical fields such as protein adsorption and bone regeneration.

amorphous Magnesium Phosphate flower like hierarchical nanostructures microwave assisted rapid synthesis using fructose 1 6 bisPhosphate trisodium salt as an organic phosphorus source and application in protein adsorption
RSC Advances, 2015Co-Authors: Chao Qi, Bingqiang Lu, Jin Wu, Feng ChenAbstract:Magnesium Phosphate, as an alternative to well-known calcium Phosphate biomaterials and an excellent candidate for biomedical applications, has aroused interest in recent years due to its outstanding biocompatibility and biodegradability. However, to the best of our knowledge, the microwave-assisted hydrothermal rapid synthesis of amorphous Magnesium Phosphate hierarchical nanostructures using fructose 1,6-bisPhosphate trisodium salt as an organic phosphorus source has not been reported. Herein, we report a simple, one-step and low-cost microwave-assisted hydrothermal rapid synthesis of amorphous Magnesium Phosphate flower-like hierarchical nanostructures (AMPFHNs) by using fructose 1,6-bisPhosphate trisodium salt (FBP) as an organic phosphorus source. The as-prepared AMPFHNs are formed by self-assembly with amorphous Magnesium Phosphate nanosheets with a thickness of about 10 nm. The use of FBP as an organic phosphorus source and the microwave hydrothermal time as well as microwave hydrothermal temperature are important factors in the synthesis of AMPFHNs. The AMPFHNs have a high cytocompatibility, and exhibit an excellent ability to promote the adhesion and spreading of the MC-3T3 osteoblasts, and have a relatively high protein adsorption ability using hemoglobin (Hb) as a model protein. The as-prepared AMPFHNs are promising for application in various biomedical fields.

Journal of Materials Chemistry B, 2014Co-Authors: Yingjie Zhu, Guanjun Ding, Tuanwei Sun, Feng ChenAbstract:Magnesium Phosphate biomaterial, as an alternative to well-known calcium Phosphate biomaterials, is an excellent candidate for biomedical applications, owing to its outstanding biocompatibility and biodegradability. Herein, we report a simple strategy for the rapid synthesis of Magnesium Phosphate hydrate nanosheets (MPHSs) using the microwave-assisted hydrothermal method. This method is facile, rapid, surfactant-free and environmentally friendly. The product shows an excellent ability to promote osteoblast MC-3T3 adhesion and spreading, which indicates high biocompatibility. Moreover, the as-prepared MPHSs are explored for potential applications in the loading and release of the anticancer drug and protein adsorption, using docetaxel as a model anticancer drug and hemoglobin (Hb) as a model protein. The experiments indicate that the as-prepared MPHSs have a relatively high protein adsorption capacity and a high ability to damage tumor cells after loading docetaxel. Thus, the as-prepared MPHSs are promising for applications in various biomedical fields such as drug delivery and protein adsorption.
