A Fractal Model of Cracking of Cement Matrix Composites
The modern methods of materials (including cement matrix materials) design and testing impose the application of an approach appropriate to materials engineering. A quantitative description of the association between the properties of these materials and

Cements based on kaolinite waste [PDF]
The cement industry involves high-energy consumption that generates high CO2 emissions into the atmosphere. Environmental concerns can be addressed by replacing parts of Portland cement clinkers with pozzolanic materials in mortars and concrete.

Washing of iron ore fines and slime (10% and 25% w/v, slurry concentrations) with two types of surface‐active agents (sodium humate (synthesized) and AD 200 (commercial)) at varying concentrations at pH 8 was conducted for ascertaining the efficacy of dispersants in beneficiating the low‐grade iron ores. The beneficiation process follows the “selective

Nowadays, researchers have been on the lookout for eco‐sustainable additives such as agro/industrial waste in concrete in order to offset the carbon footprint created by cement manufacturing. However, it has been said that the use of agro/industrial‐waste‐based cementitious materials in concrete improves its quality.
