Influence of HPMC & VAE on the Performance of Dry-Mixed Mortars

The mechanism of HPMC and VAE on the properties of dry-mixed mortar was studied by using self-developed crack resistance test method & etc. The results show that HPMC will significantly increase the water demand, VAE can significantly reduce the water, and the mixed result is higher than the sum of the two. Both HPMC and VAE can retain water, but the difference is very large, and the result of compound mixing is the superposition of two. HPMC will significantly reduce the wet unit weight, while VAE will slightly reduce the wet unit weight. The effect of compound blending is the superposition of the two. HPMC can significantly reduce the compressive strength and flexural strength; VAE can significantly improve the flexural strength, and the compressive strength can be increased when the dosage is high. The result of compound mixing is the sum of the two. HPMC can slightly improve the bond strength, while VAE can significantly improve the original bond strength with mortar. HPMC has a more significant effect on the compression ratio, and VAE has a more significant effect on the crack resistance; The compound addition is beneficial to the improvement of crack resistance.
