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
The present invention relates to a kind of cement, relate in particular to a kind of cracking resistance cement.
Background technology
Cement is the important source material of preparing concrete and various cement products thereof, is also the indispensable building materials of civil construction project.Although the cement concrete of common cement sclerosis has very high ultimate compression strength, also has a lot of defects, such as shortcomings such as tensile strength are low, impact resistance is poor, resistance to cleavage is poor.In the lower basic unit of some intensity, traditional way is after cement concrete solidifies, then coats waterproof coating layer on cement layer surface., there is very large potential safety hazard in waterproof layer smooth surface, therefore occurred cracking resistance cement-base waterproof coating, by modifications such as dispersed rubber powder, properties-correcting agent when workman's working aloft.After solidifying, sand-cement slurry is become and is had certain flexibility by perfect rigidity, but simultaneously, the cracking resistance of cement layer newly can decline to some extent.
The cup shake existing in cement and thermal cracking As time goes on development become large fracture, these be on the rise and the serious cracking that increases affected concrete weather resistance.Simultaneously the existence in crack, causes waterproof failure, makes cement matrix deteriorated until destroy, so the cracking of cement matrix is to be also badly in need of the technical barrier that solves in construction work.
Mortar is common material for building, belongs to the indispensable material in building operation.Many defects that easily occur crackle in various mortars, had both affected attractive in appearancely, directly affected again the performances such as bonding strength.
Summary of the invention
For solving the deficiencies in the prior art and meeting building industry needs, the invention provides a kind of cracking resistance cement of improvement.
A cracking resistance cement, comprise the component of following mass fraction: 48～52 parts of silicate cements, 35～43 parts of quartz sands, 1～2 part of hydrophober, 6～12 parts of dispersed rubber powders, 1～8 part of nylon fiber, 2～3 parts, glass fibre, 5～8 parts of polyethylene rubber powders, 1～10 part of elastic emulsion, 1～10 part of light heat-insulating material, 35～40 parts, water.
Preferably, described dispersed rubber powder is 8～10 parts.
Preferably, described elastic emulsion is 2～7 parts.
Preferably, 45～90 object quartz sands account for 30～40% of described quartz sand.
Preferred, described light heat-insulating material is one or more in double glazing microballon, closed perlite, pearlstone, expanded vermiculite, aluminium silicate wool, sepiolite.
The cracking resistance cement of improvement provided by the present invention, through rational compatibility, has further increased function and the antiskid function of the cracking resistance after cement layer solidifies.Can effectively increase the toughness of cement layer, minimizing wall crazing, crack enter the possibility of water.Its good water resistance makes body of wall not perishable simultaneously, and cracking place is difficult for further weathering.
