Concrete admixture and application thereof in concrete containing machine-made sand
The invention provides a concrete admixture comprising a water reducing agent, dipropyl amine and sodium hexametaphosphate. The invention also provides an application of the admixture in concrete containing machine-made sand. The concrete admixture provided by the invention is prepared by compounding the water reducing agent with dipropyl amine and sodium hexametaphosphate so as to ensure that the concrete has good workability without causing water bleeding and segregating phenomena, and thus the later working performance of the concrete can be ensured. The concrete admixture provided by the invention is particularly suitable for the machine-made sand concrete with relatively high content of mud and stone powder, and can be used for greatly improving the mechanical performance and construction performance of the machine-made sand concrete so as to ensure that the machine-made sand concrete can be used for completely replacing natural sand concrete to be applied to the field of architectures; and the concrete admixture can be used for reducing the mining of natural sand, and is more beneficial to the requirements of sustainable development.
