Study on Stay-in-Place Cement Formwork and the Application

Abstract:

Three contents are included in this paper: 1) Through orthogonal experiment, some principal materials and their use levels which will influence performances of cement formwork are optimized and researched. A matched group could bring best comprehensive performance plate suitable to be used as construction formwork is obtained. 2) Through study the strength retention rate of specimens after immersing in various solutions for different ages, the alkali resistance property and lasting quality of the formwork are investigated, and it indicates that during general serviceable life specified by China Structure Design Code, the failure probability due to durability is very low. 3) Through mechanical experiments of combined slabs with different conjoint methods, cooperation performance between formwork and concrete is studied, which prove composite slabs work well.
