Abstract

The invention relates to cement, and particularly relates to anti-cracking cement. The improved anti-cracking cement comprises the following components in parts by weight: 48-52 of Portland cement, 35-43 parts of quartz sand, 1-2 parts of water repellent, 6-12 parts of dispersibility rubber powder, 1-8 parts of nylon fiber, 2-3 parts of glass fiber, 5-8 of polyethylene rubber powder, 1-10 parts of elastic emulsion, 1-10 parts of lightweight thermal insulation material and 35-40 parts of water. After the improved anti-cracking cement is solidified, the anti-cracking function and the skid resistance function of the improved anti-cracking cement provided by the invention are further improved through reasonable combination. The toughness of a cement layer can be effectively improved, and the possibility of wall cracking and crack water entry is reduced. Meanwhile, as the water resistance of the improved anti-cracking cement is relatively good, walls are difficult to corrode, and cracking parts are difficult to further weather.

Description

technical field [0001] The invention relates to a kind of cement, in particular to a kind of anti-cracking cement. Background technique [0002] Cement is an important raw material for the preparation of concrete and various cement products, and is also an indispensable building material for civil engineering. Although ordinary cement has high compressive strength in hardened cement concrete, it also has many defects, such as low tensile strength, poor impact resistance, and poor crack resistance. In some low-strength bases, the traditional method is to apply a waterproof coating layer on the surface of the cement layer after the cement concrete is cured. The surface of the waterproof layer is smooth, and there is a great safety hazard when workers work at heights. Therefore, crack-resistant cement-based waterproof coatings have appeared, which are modified by dispersible rubber powder and modifiers. After curing, the cement mortar changes from complete rigidity to a certa...
