Thickening concrete containing bentonite and preparation method thereof
The invention discloses bentonite-containing thickening concrete and a preparation method thereof, and relates to the technical field of concrete preparation, the bentonite-containing thickening concrete is prepared from the following raw materials by weight: 300-400 parts of cement, 200-300 parts of modified bentonite, 100-150 parts of modified loess, 600-700 parts of coarse aggregate, 400-500 parts of fine aggregate, 50-100 parts of a fiber additive, 2-4 parts of a water reducer, and 150-200 parts of water. The preparation method specifically comprises the following steps: S1, weighing raw materials in parts by weight for later use; s2, the coarse aggregate and the fine aggregate are mixed and stirred for 20-30 min, and a mixture A is obtained; s3, cement, modified bentonite, modified loess, a water reducing agent and water are mixed and stirred for 30-50 min, and a mixture B is obtained; s4, mixing the mixture A, the mixture B and a fiber additive, and stirring for 30-40 minutes to obtain the thickening concrete. The concrete is sticky, convenient to construct, good in mechanical property, not prone to cracking, good in anti-seepage effect and capable of being widely applied to anti-seepage engineering or grouting engineering.
本发明公开了一种含膨润土的增稠型混凝土及其制备方法，涉及混凝土制备技术领域，由下述重量份数的原料制备而成：水泥300‑400份、改性膨润土200‑300份、改性黄土100‑150份、粗集料600‑700份、细集料400‑500份、纤维添加剂50‑100份、减水剂2‑4份、水150‑200份。具体包含以下步骤：S1：按重量份数称取原料备用；S2：将粗集料和细集料混合，搅拌20‑30min，得到混合料A；S3：将水泥、改性膨润土、改性黄土、减水剂与水混合，搅拌30‑50min，得到混合料B；S4：将混合料A、混合料B与纤维添加剂混合，搅拌30‑40min，得到增稠型混凝土。本发明的混凝土黏稠便于施工、力学性能良好、不易开裂、防渗效果好，可广泛应用于防渗工程或注浆工程中。
