Improved type composite cement

Abstract

An improved composite cement, which is made of the following raw materials in parts by weight: 30-45 parts of ordinary portland cement, 4-8 parts of hydrogen peroxide, 1-1.5 parts of polypropylene fiber, 0.6-0.9 parts of hydrochloric acid, wheat bran 5‑8 parts, cetyl ethoxy sultaine 3‑7 parts, sepiolite 2‑4 parts, river sand 12‑16 parts, styrene-butadiene rubber emulsion 2‑6 parts, tourmaline powder 7‑ 15 parts, 4-6 parts of fly ash, 2-4 parts of glass fiber powder, 1.5-3.2 parts of fluid loss reducer, 0.2-0.4 parts of silane coupling agent, 0.6-2.2 parts of defoamer, 10-16 parts of silicon powder , 8-13 parts of iron oxide, 1-3 parts of diatomaceous earth. The beneficial effects of the invention are: the improved composite cement of the invention has the functions of high-efficiency waterproof, corrosion resistance, crack resistance, etc., increases the strength of the cement, has high bonding strength, long service life and high reliability.

Description

technical field [0001] The invention relates to an improved composite cement. Background technique [0002] As an important cementing material, cement is widely used in civil engineering, water conservancy, national defense and other projects. The invention of cement is the result of human beings' continuous accumulation in long-term production practice, and it is developed on the basis of ancient building materials. It has gone through a long historical process. In the process of cement development, Portland cement plays an important role in capital construction projects in terms of output and use. However, due to the inherent performance and characteristics of ordinary Portland cement, it determines It cannot meet the current needs, nor can it meet the needs of modern construction projects and new construction technologies. It has the problems of weak surface wear resistance, low strength, and poor corrosion resistance, and needs further improvement. Contents of the in...
