Experimental on properties of cement mortar with different quantity of fly ash under low water-cement ratio

Purpose research on properties of cement mortar with different quantity of fly ash under low water-cement ratio.The conclusion as the fluidity of test samples same,the content of admixture of cement mortar decreased with the quantity of fly ash increasing under low water-cement ratio,the affect of fly ash to cement mortar under the different age,in the early days of hydration reaction,the compressive strength of cement mortar with different quantities of fly ash was lower than standard cement mortar,and the compressive strength decrease with the quantity of fly ash increasing,the effect of different quantity of fly ash on cement mortar was different,in engineering,the properly quantity of fly ash should be selected to improve the compressive strength and flexural strength of building structure.
