Abstract
Sisal fiber modified foamed concrete was prepared with ordinary Portland cement and vegetable protein foaming agent as the base material and sisal fiber as the modifier. The distribution of fibers in the sample changes. The results show that when the fiber content is 0.75% and the fiber length is 5mm, the mechanical properties of foamed concrete are improved most obviously, and the respectively. Sisal fiber can effectively improve the shrinkage of foamed concrete. The longer sisal fiber is, the smaller the drying shrinkage of modified foamed concrete is. From the optical photos of concrete, it can be seen that at the same mixing amount (1%), fibers with lengths of 5mm and 10mm are more evenly dispersed than those with lengths of 15mm, which have little impact on the bubble holes.
