  • high volume Cement replaCement by environmental friendly industrial by product palm oil clinker powder in Cement lime masonry mortar
    Journal of Cleaner Production, 2018
    Co-Authors: Ramappa Ramesh Nayaka, Johnson U Alengaram, Mohd Zamin Jumaat, Sumiani Yusoff, Mohammed Fouad Alnahhal
    Abstract:

    Abstract Cement-lime based mortar is extremely popular for a wide range of construction around the world and conserving natural resources used in the production of such material is of capital importance. Identification of alternative materials from palm oil based industrial by-products enabled researchers to use palm oil clinker powder (POCP) as a Cement replaCement material; in this research work, POCP was used as Cement replaCement material in masonry mortar. The physical, chemical properties and SEM of POCP were analyzed to investigate the feasibility of utilizing POCP as Cement replaCement for up to 80%. Based on the feasibility study, final mortar mixes were prepared utilizing 40% of POCP. Further investigations were carried on fresh, mechanical and bond properties of mortar. The hardened properties for mechanical performance and ultrasonic pulse velocity (UPV) investigated in water and air cured regimes show that up to 40% of Cement could be replaced to obtain the requisite compressive strength of 12.4 MPa for Cement-lime mortar. Further, POCP ground to more number of cycles had minor impact on the mechanical properties. The investigation on the potential use of POCP as Cement replaCement confirmed the potentiality through energy saving, cost effective and cleaner environment.

    Co-Authors: Ali A Aliabdo, Abd Elmoaty Abd M Elmoaty, Ahmed Y Aboshama
    Abstract:

    Abstract The aim objective of this work is to study of the use of waste glass powder obtained from grinding of crushed containers and building demolition to produce glass powder blended Cement as concrete additives. The pozzolanic activity of glass powder and properties of glass powder blended Cement were evaluated. Also, the effect of using glass powder as Cement replaCement and as Cement addition was studied in the term of physical and mechanical properties. The considered glass powder contents were 0.0%, 5.0%, 10.0%, 15.0%, 20.0% and 25.0% by weight of Cement. The test results showed that the glass powder had pozzolanic characteristic and the use of glass powder had insignificant effect on setting time and Cement expansion. The use of 10% glass powder as Cement replaCement enhanced the mortar compressive strength by about 9.0%. Also, generally, the use of glass powder as Cement replaCement up to 15.0% enhanced the properties of concrete modified with glass powder. Finally, the use of 15% glass powder as Cement addition increased concrete compressive strange by 16.0% in average and achieved better performance compared with as Cement replaCement.

  • re use of waste marble dust in the production of Cement and concrete
    Construction and Building Materials, 2014
    Co-Authors: Ali A Aliabdo, Abd Elmoaty Abd M Elmoaty, Esraa M Auda
    Abstract:

    Abstract The main objective of this research is to investigate the possibility of utilizing waste marble dust (MD) in Cement and concrete production. The research work was divided into two sections. The first section deals with the properties of Cement modified with marble dust (marble dust blended Cement), whereas the second section discusses the properties of concrete contained marble dust as a Cement replaCement and as a sand replaCement (Cement addition). The replaCement ratios which have been studied were 0.0%, 5.0%, 7.5%, 10.0% and 15% by weight. Water to powder ratio (w/p) or water to Cement ratio (w/c) were 0.50 and 0.40 in case of Cement replaCement and in case of sand replaCement respectively. Physical, mechanical and chemical properties of Cement and concrete modified with marble dust were investigated. In addition, TGA, XRD and SEM analysis were performed. Test results of Cement paste and Cement mortar indicate that the marble dust blended Cement remains within the acceptable ranges of the Egyptian standards. Also, generally, the use of marble dust in concrete production as Cement replaCement or as sand replaCement (Cement addition) gradually enhances both of the mechanical and physical properties of concrete especially with lower w/c ratio. Marble dust showed a filler effect in concrete and had no noticeable role in the hydration process. Yet, concrete made with marble dust as sand replaCement achieved better performance compared to concrete made with marble dust as Cement replaCement.

  • mechanical properties and corrosion resistance of concrete modified with granite dust
    Construction and Building Materials, 2013
    Co-Authors: Abd Elmoaty Abd M Elmoaty
    Abstract:

    Abstract Granite dust is a waste material produced during cutting and polishing process of granite products. This research work presents an experimental investigation on physical, mechanical properties and reinforCement corrosion resistance of concrete modified with granite dust. The Cement pastes modified with granite dust were examined using TGA, X-ray and SEM. Granite dust Cement replaCement or addition of 5.0%, 7.5%, 10.0% and 15.0% were used. The test results showed an improvement on concrete compressive strength at 5.0% granite dust as Cement replaCement and improvement on compressive strength at most levels of granite dust as Cement addition. The tensile strength test results are confirmed the test results of concrete compressive strength. Also, the use of 5.0% granite dust increased the corrosion cracking time and no significant reduction in cracking time was observed at granite dust contents greater than 5.0%. Insignificant changes in hydration products, microstructure and degree of hydration due to using granite dust were observed. Finally, a reduction in water Cement ratio around 0.03 was enough to cancel the reduction in concrete compressive strength as a result of granite dust up to 15.0% as Cement replaCement.

  • high volume Cement replaCement by environmental friendly industrial by product palm oil clinker powder in Cement lime masonry mortar
    Journal of Cleaner Production, 2018
    Co-Authors: Ramappa Ramesh Nayaka, Johnson U Alengaram, Mohd Zamin Jumaat, Sumiani Yusoff, Mohammed Fouad Alnahhal
    Abstract:

    Abstract Cement-lime based mortar is extremely popular for a wide range of construction around the world and conserving natural resources used in the production of such material is of capital importance. Identification of alternative materials from palm oil based industrial by-products enabled researchers to use palm oil clinker powder (POCP) as a Cement replaCement material; in this research work, POCP was used as Cement replaCement material in masonry mortar. The physical, chemical properties and SEM of POCP were analyzed to investigate the feasibility of utilizing POCP as Cement replaCement for up to 80%. Based on the feasibility study, final mortar mixes were prepared utilizing 40% of POCP. Further investigations were carried on fresh, mechanical and bond properties of mortar. The hardened properties for mechanical performance and ultrasonic pulse velocity (UPV) investigated in water and air cured regimes show that up to 40% of Cement could be replaced to obtain the requisite compressive strength of 12.4 MPa for Cement-lime mortar. Further, POCP ground to more number of cycles had minor impact on the mechanical properties. The investigation on the potential use of POCP as Cement replaCement confirmed the potentiality through energy saving, cost effective and cleaner environment.

  • feasibility study of high volume slag as Cement replaCement for sustainable structural lightweight oil palm shell concrete
    Journal of Cleaner Production, 2015
    Co-Authors: Kim Hung Mo, Johnson U Alengaram, Mohd Zamin Jumaat, Soon Poh Yap
    Abstract:

    This paper presents a study on the use of high volume slag as a Cement replaCement material, and waste oil palm shell (OPS) as a lightweight aggregate to produce a sustainable lightweight concrete (LWC). In order to establish the feasibility of such concrete for structural purposes, the first part of the paper deals with the investigation of the mechanical and bond properties of OPS concrete (OPSC) with varying slag content. The results showed that even though an increase in the slag content led to the reduction in the strength, the OPSC with slag as a 60% Cement replaCement material exhibited compressive and splitting tensile strengths of 25 and 2.3 MPa, respectively, which exceeded the minimum stipulated strength required for structural LWC. In addition, the use of 60% slag in OPSC showed significant benefits in terms of the reduced Cement consumption with improvement in the strength efficiency by almost 2-fold compared to that without slag. On the other hand, it was found that the slag content, albeit as high as a 60% Cement replaCement level, did not show any significant adverse effects on the normalized bond strength, failure mode, bond strength-slip curve and slip at the ultimate bond strength of the OPSC. To further justify the suitability of the OSPC for structural application, the second part of the paper focuses on the experimental investigation of the flexural behaviour of the actual full-scale reinforced concrete beams. From the flexural tests, it was observed that there were no negative effects on the ultimate moment capacity, failure mode and moment-deflection behaviour of the reinforced concrete beams upon Cement replaCement with up to 60% slag. Therefore, the utilization of high volume slag-lightweight OPSC could be recommended for actual structural purposes.
