selected thermoanalytical methods and their applications from medicine to Construction Part i
Journal of Thermal Analysis and Calorimetry, 2007Co-Authors: S C Mojumdar, Mohini Sain, R C Prasad, L Sun, J E S VenartAbstract:There are many thermoanalytical techniques but only several of them such as thermogravimetric analysis (TG), high resolution thermogravimetric analysis (Hi-Res™ TG), derivative thermogravimetry (DTG), differential thermal analysis (DTA), calorimetry, differential scanning calorimetry (DSC), modulated differential scanning calorimetry (MDSC), evolved gas analysis (EGA), transient thermal analysis (TTA) and thermal conductivity (k) have selected to be discussed in this paper. Simultaneous thermal analysis (STA) is ideal for investigating issues such as the glass transition of modified glasses, binder burnout, dehydration of ceramic materials or decomposition behaviour of inorganic building materials, also with gas analysis. Selected applications of various thermoanalytical techniques from medicine to Construction have also been discussed in this paper.

binders alternative to portland cement and waste management for sustainable Construction Part 2
Journal of Applied Biomaterials & Functional Materials, 2018Co-Authors: Luigi Coppola, Marta Cappai, Alberto Belli, Maria Chiara Bignozzi, Francesco Bolzoni, Tiziano Bellezze, Andrea Brenna, Marina Cabrini, Sebastiano Candamano, Domenico CaputoAbstract:The paper represents the "state of the art" on sustainability in Construction materials. In Part 1 of the paper, issues related to production, microstructures, chemical nature, engineering properties, and durability of mixtures based on binders alternative to Portland cement were presented. This second Part of the paper concerns the use of traditional and innovative Portland-free lime-based mortars in the conservation of cultural heritage, and the recycling and management of wastes to reduce consumption of natural resources in the production of Construction materials. The latter is one of the main concerns in terms of sustainability since nowadays more than 75% of wastes are disposed of in landfills.

binders alternative to portland cement and waste management for sustainable Construction Part 1
Journal of Applied Biomaterials & Functional Materials, 2018Co-Authors: Luigi Coppola, Marta Cappai, Alberto Belli, Maria Chiara Bignozzi, Francesco Bolzoni, Tiziano Bellezze, Andrea Brenna, Marina Cabrini, Sebastiano Candamano, Domenico CaputoAbstract:This review presents “a state of the art” report on sustainability in Construction materials. The authors propose different solutions to make the concrete industry more environmentally friendly in order to reduce greenhouse gases emissions and consumption of non-renewable resources. Part 1—the present paper—focuses on the use of binders alternative to Portland cement, including sulfoaluminate cements, alkali-activated materials, and geopolymers. Part 2 will be dedicated to traditional Portland-free binders and waste management and recycling in mortar and concrete production.

Rubble masonry concrete dam design and Construction - Part i : new-generation RMC dams in SA, as illustrated through the Bakubung, Welgevonden and Genadendal dams : technical paper
Joernaal van die Suid-Afrikaanse Instituut van Siviele Ingenieurswese, 1998Co-Authors: Q.h.w. ShawAbstract:For a little over a decade, arch dams of various configurations have been constructed in Zimbabwe using a variation of traditional masonry technology, termed rubble masonry concrete (RMC). Bringing this technology to South Africa in the 1990's, we find a dam building material and method that is extremely cost-effective, produces a durable, low-maintenance dam wall and is Particularly labour-intensive. The author has been involved in a number of RMC dam projects to date, three of which - the Bakubung, Welgevonden and Genadendal Dams - have been taken to, or beyond, the detailed design stage. In this paper the experience gained and Particularly interesting phenomena observed in the design and Construction of RMC dams are presented.

rubble masonry concrete dam design and Construction Part ii proposed design standards and related influences technical paper
Joernaal van die Suid-Afrikaanse Instituut van Siviele Ingenieurswese, 1998Co-Authors: Q.h.w. ShawAbstract:Rubble masonry concrete (RMC) dam Construction is likely to become increasingly prevalent in South Africa, Particularly in view of our current need for job creation and skills development. In light of the fact that design technology has to date been developed largely on empirical grounds and Construction has included some fairly ambitious structural configurations, a need is perceived for a more analytical approach to RMC dam design. This paper discusses appropriate design methodologies for RMC arch dams, on the basis of previous design and Construction practices and in relation to experience gained on recent structures designed and constructed in South Africa.

a conceptual model that simulates the influence of thermal inertia in building structures
Energy and Buildings, 2013Co-Authors: Jonathan Karlsson, Lars Wadso, Mats ObergAbstract:The energy use for maintaining comfortable indoor temperatures are to a certain extent dependent on the thermal storage capacity of materials in contact with the indoor air. This article describes a conceptual model for investigating the effects of increasing the thermal storage capacity of building materials. A building is modeled as an exterior wall, an indoor air volume and a thermally heavy inner wall. The input of thermal energy (heating, solar) is also included, as is a varying external temperature. The result is shown in three-dimensional graphs with different output variables of interest as functions of volumetric heat capacity and thermal conductivity of the material in the heavy Construction Part (with a standard concrete as a reference). Output variables of interest are for example energy consumption, peak power consumption and thermal comfort parameters. Influence of factors such as the thickness of the interior wall, wall surface area, and the influence of free solar radiation can be tested. The aim is to present a minimal and thus fully comprehensible model that can be used as a qualitative tool to investigate the influence of thermal mass on building performance. The model was tested for a cold-climate case and the results show that passive energy storage through high thermal mass can significantly change the power consumption pattern, which can give significant benefits, while the total energy consumption in most cases is not much influenced.
