Mix Design and Performance Test of High-Strength Fluid and Micro-Expansion Concrete with the Additive of CAN

Abstract:

Article Preview

High-strength flowing concrete is made of large volume of gelled materials and high rate of sand, but low content of coarse aggregate and small grain diameter, which makes it easy to have a greater contraction, resulting in reduced strength and durability of concrete[4] .So the right amount of expansion admixture is needed to ensure that there is no shrinkage or micro-expansion of the concrete. In this paper, the right mixing ratio of the concrete will be achieved, which is consistent with needs of project, by designing tests of mixing ratio of different gelled materials (cement, fly ash, silica fume and expansion admixture) and mix design of high-strength fluid and micro-expansion concrete with the CAN admixture inside and by measuring its performance.
