Cause of alkali-silica reaction. ASR is the most common form of alkali-aggregate reaction (AAR) in concrete; the other, much less common, form is alkali-carbonate reaction (ACR). ASR and ACR are therefore both subsets of AAR. ASR is caused by a reaction between the hydroxyl ions in the alkaline cement pore solution in the concrete and reactive ...

Permeation grouting is a ground improvement method commonly used for strengthening and/or reducing permeability of soils with minimal disturbance to the existing soil structure. Cement/microfine cement grouts are the most common form of grouts used for sandy soils; however, the effectiveness and uniformity of the grout propagation is …
1. Introduction. Geopolymer concrete has been explored as an alternative sustainable concrete in recent years. Significant research has been conducted to understand the process of geopolymerisation and the resulting strength gain mechanisms [1].Studies have suggested that geopolymerisation is a result of reaction between …
Look for the second installment in the July issue. Every load of ready-mixed concrete comes with a delivery ticket full of useful information, if you know how to crack the secret code. Critical information includes identifying the mix, batch, and cumulative volume; help on checking yield; admixtures; and the amount of water that can be added ...
Abstract. Cement and Casing integrity across the surface aquifers is as imperative as against the reservoir section, to avoid ground water communication. Zonal isolation among aquifers is obligatory as per local regulations. Understanding the expected cement quality in the intermediate casing across aquifers is desirable. It is essential to …

Portland cement have to hydrate in cold climates in some particular conditions. Therefore, a better understanding of cement hydration under low temperatures would benefit the cement-based composites application. In this study, Portland cement was, therefore, kinetically and thermodynamically simulated based on a simple kinetics …
Cement history. Throughout history, cementing materials have played a vital role and were used widely in the ancient world. The Egyptians used calcined gypsum as a cement and the Greeks and Romans used lime made by heating limestone and added sand to make mortar, with coarser stones for concrete. The Romans found that a cement could be made ...
