Preparation and Mixture Ratio Design of Foam Concrete with Lightweight Tailings

In this paper, the preparation technology and improved the mixture ratio design method of foam concrete with lightweight tailings have been studied. Based on the review, the following research needs have been identified: (i) to calculate the amount of lightweight tailings by the binder materials content, (ii) to calculate additional water by the water absorption of lightweight tailings saturated surface dry condition, (iii) to calculate foam stabilizer content by the weight of foaming agent. Foam should be measured by volume. By testing the wet density of foam concrete paste to accurately control the amount of foam. The foam concrete mixed with a certain amount of lightweight tailings not only can significantly reduce the content of cement, reduce cost, but also can improve the performance of foam concrete.
