Sand washing sludge baking-free brick and preparation process thereof
The invention relates to the field of baking-free bricks, and particularly discloses a sand washing sludge baking-free brick and a preparation process thereof.The sand washing sludge baking-free brick is prepared from, by weight, 500-550 parts of sand washing sludge; 80 to 150 parts of cement; 280 to 320 parts of stone powder; 20 to 50 parts of quick lime; 30-50 parts of a curing agent; 140 to 200 parts of modified straw fiber; 50 to 100 parts of a binder; 5-20 parts of a water reducing agent; 10-20 parts of an early strength agent; and 3-11 parts of water, wherein the modified straw fiber is a silane and acrylate composite modified straw fiber. The highest compressive strength and breaking strength of the sand washing sludge baking-free brick are 42.0 MPa and 7.73 MPa respectively, the lowest water absorption rate and stacking density are 2.39% and 1.51 kg/m < 3 > respectively, and the mechanical property of the sand washing sludge baking-free brick is improved.
本申请涉及免烧砖领域，具体公开了一种洗砂污泥免烧砖及其制备工艺，其中洗砂污泥免烧砖包括以下重量份原料，洗砂污泥500‑550份；水泥80‑150份；石粉280‑320份；生石灰20‑50份；固化剂30‑50份；改性秸秆纤维140‑200份；粘结剂50‑100份；减水剂5‑20份；早强剂10‑20份；水3‑11份，改性秸秆纤维为硅烷和丙烯酸酯复合改性秸秆纤维。本申请制备得到的洗砂污泥免烧砖的抗压强度、抗折强度最高分别为42.0MPa、7.73MPa，吸水率、堆积密度最低分别为2.39%、1.51kg/m3，提高了洗砂污泥免烧砖的力学性能。
