Low-elastic-modulus fiber reinforced cement-based composite material
The invention relates to a low-elastic-modulus fiber-reinforced cement-based composite material which is specifically prepared from the following raw materials in parts by weight: 292 parts of cement, 156 parts of fine river sand, 18 parts of waste rubber particles, 39 parts of fly ash, 58 parts of blast furnace slag, 92 parts of water, 8.4 parts of polyethylene fibers, 0.5 part of a cellulose thickening agent and 8.3 parts of a polycarboxylic acid high-performance water reducing agent. The method has the advantages that the elastic modulus and the inherent frequency of the ECC can be reduced, the crack resistance, the impact resistance and the noise reduction performance of the ECC are effectively improved, meanwhile, the bending deflection deformation capacity of the ECC is improved, the crack width is reduced, and the durability of the ECC is facilitated.
本发明涉及一种低弹模纤维增强水泥基复合材料，具体由以下重量份的原料组成：水泥292份、细河砂156份、废弃橡胶粒18份、粉煤灰39份、高炉矿渣58份、水92份、聚乙烯纤维8.4份、纤维素增稠剂0.5份、聚羧酸高性能减水剂8.3份。本发明的优点在于：可以降低ECC弹性模量及固有频率，有效提高其抗裂性能、抗冲击及降噪性能，同时提高ECC的弯曲挠曲变形能力，减少裂缝宽度，利于其耐久性。
