The experiment results show that these three kinds of additives can improve sulphate attack resistance of the concrete and the order of their efficiency from high to low is silica fume,slag and fly ash;the development of mortar expansion value is closely related to the degree of sulphate attack resistance of the concrete;integrated assessing two concrete properties: mortar expan.

To take fly-ash concrete block and autoclaved fly-ash brick as fly-ash wall materials and take vitrified microsphere heat insulation mortar as heat insulation materials,four test specimens were selected to study thermal insulation performance of fl.
