摘要
该文采用喷水硬化工艺制造了玻璃纤维编织网增强水泥基板材,试验研究了配网率和纤维编织网定位方式对其抗弯性能的影响。结果表明:玻璃纤维编织网可显著改善喷水成型水泥基板材的抗弯性能。随着配网率的增加,纤维网增强水泥基板材的抗弯强度和极限挠度明显提高。配网率为1.0%时,磁铁定位双层纤维网增强水泥基板材抗弯强度达10.64MPa,是无增强纤维网板材的3倍;极限挠度达6.74mm,是无增强纤维网板材的8倍。该工艺可解决需要快速搭建又无预拌条件工程的施工问题。
Textile reinforced cementitious composite board was produced using a sprinkling water hardening technique.Test measured the effect of the textile ratio and textile location on the flexural performance of the board.The results show that the flexural behavior of the board made with the sprinkling water hardening technique was greatly improved by adding the glass fibers.As the textile ratio increases,the flexural strength and ultimate deflection of the textile glass reinforced cementitious board are greatly increased.The flexural strength of boards with 1.0% textile ratio can reach 10.64 MPa,which is 3 times higher than the boards without textiles,and the ultimate deflection is 6.74 mm,which is 8 times higher than that of the boards without textiles.The sprinkling water hardening technique may solve construction problems where there is no way to directly mix cement with water.
