Low-carbon low-shrinkage high-strength high-ductility cement-based composite material and preparation method thereof
The invention discloses a low-carbon low-shrinkage type high-strength and high-ductility cement-based composite material and a preparation method thereof. The low-carbon low-shrinkage type high-strength and high-ductility cement-based composite material comprises the following components in parts by weight: 650-750 parts of cement, 100-150 parts of silica fume, 500-600 parts of fly ash, 400-450 parts of yellow sand, 0-100 parts of gypsum, 30-40 parts of a high-efficiency water reducing agent, 15-25 parts of synthetic fibers and 200-250 parts of water. The preparation method comprises the following steps: weighing the cement, the silica fume, the fly ash, the yellow sand, the gypsum, the high-efficiency water reducing agent, the synthetic fibers and the water in parts by weight; sequentially pouring the cement, the silica fume, the fly ash, the gypsum and the yellow sand into a drum-type stirrer, and stirring to obtain a dry mixture A; adding a high-efficiency water reducing agent into water, uniformly stirring, adding into the dry mixture A, and mixing and stirring to obtain a mortar material B; and finally dispersing synthetic fibers into the mortar material B, and stirring to obtain the low-carbon low-shrinkage high-strength high-ductility cement-based composite material. The cement-based composite material disclosed by the invention has good mechanical strength and toughness and also has the characteristics of low carbon and low shrinkage, and the preparation method is simple in process and few in raw material variety.
本发明公开了一种低碳低收缩型高强高延性水泥基复合材料及其制备方法，各组分按照重量份计：水泥650‑750份、硅灰100‑150份、粉煤灰500‑600份、黄砂400‑450份、石膏0‑100份，高效减水剂30‑40份、合成纤维15‑25份、水200‑250份；还涉及一种制备方法：按重量份称取水泥、硅灰、粉煤灰、黄砂、石膏、高效减水剂、合成纤维和水；将水泥、硅灰、粉煤灰、石膏、黄砂依次倒入滚筒式搅拌机中搅拌，得到干混料A；然后将高效减水剂加入水中搅拌均匀，加入干混料A中，混合搅拌得到砂浆料B；最后将合成纤维分散撒入砂浆料B内，搅得到低碳低收缩型高强高延性水泥基复合材料。本发明的水泥基复合材料，具有良好的机械强度和韧性，还拥有低碳低收缩特性，制备方法工序简单，原材料种类少。
