Effect of rheology-regulation additives on the formwork lateral pressure of the self-compacting concrete

摘要

This article mainly aims at to research the affect of thixotropy on the development of the formwork lateral pressure, the ultimate goal is to minimize the potential safety hazard of construction. Before the experiment, through the tests of net cement slurry, we can determine kaolin (additive) to change the influence of the liquidity of concrete. For the mixture of self-compacting concrete (SCC), set different content of admixture. Through experimental simulation measurement in 4 meters height of concrete pouring and pouring diameter of 150 mm, test the size of the lateral pressure casting the bottom template, and compare the condition of not using mineral admixtures, helps to identify the most appropriate for the amount of admixture.
