Abstract
The invention discloses kind of a cement-base infiltration crystallization water-proof material to count by weight ratio and consist of the following composition: silicate cement 100 parts, quartz sand 40-50 part, calcium hydroxide 5-10 part, active component A 1-5 part, active ingredient B1-5 part, silicon ash 5-15 part, water reducer 1-3 part, sugared calcium retardant 0.2-1 part.The present invention, compared with traditional water-proof material, has respond well, premium properties such as construction simple, low to environmental requirement, good water resistance and weather resistance etc.
Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of cement-base infiltration crystallization water-proof material.
Background technology
Skeleton construction is invented in 19 end of the centurys people, due to its have intensity high, be convenient to draw materials, the plurality of advantages such as different shape strong adaptability, make, once the favor occurring just being subject to immediately people, to have become current most of constructure body structure material.But various buildings is all contacting with dissimilar water, as water vapour, surface water, underground water etc.These water are producing harmful effect, as hygroscopic effect, wicking action, erosion action, osmosis, freeze thawing are got rid of to the structure of buildings by different way in varying degrees.The effect of this beginning gently then affects the use of buildings, heavy then shorten working life of buildings, even cannot ensure the security of the lives and property of the mankind.Publication number is that the document of CN101759414B discloses a kind of cementitious capillary crystalline waterproofing agent, and this water-resisting agent has certain impermeability and anti-steel bar corrosion, but this water-resisting agent Recipe is complicated, and cause production cost too high, economic benefit is not high.
Summary of the invention
In view of above-mentioned weak point, the object of the present invention is to provide novel cement-based water conduction fracture that a kind of Recipe is simple, cost is low and preparation method thereof, adopt cement-base infiltration crystallization water-proof material prepared by the present invention, it is coated in concrete surface uniformly by after the mixing of certain water cement ratio, in the presence of water, continuous generation penetrant crystalline reaction, form water-fast xln, block capillary channel, thus improve the degree of compactness of matrix, the impermeability of matrix is improved, effectively prevents various water to the erosion of buildings.
In order to achieve the above object, present invention employs following technical scheme: a kind of cement-base infiltration crystallization water-proof material, count by weight ratio, this water-proof material consists of the following composition:
Silicate cement 100 parts
Quartz sand 40-50 part
Calcium hydroxide 5-10 part
Active component A 1-5 part
Active ingredient B1-5 part
Silicon ash 5-15 part
Water reducer 1-3 part
Sugar calcium retardant 0.2-1 part.
Optimum, count by weight ratio, cement-base infiltration crystallization water-proof material consists of the following composition:
Silicate cement 100 parts
Quartz sand 45 parts
7 parts, calcium hydroxide
Active component A 2 parts
Active ingredient B3 part
Silicon ash 10 parts
Water reducer 2 parts
Sugar calcium retardant 0.5 part.
Its alkali content≤0.6% of described silicate cement, tricalcium aluminate content < 8%, and strength grade is for being not less than 42.5.
Described active constituent A is quick dissolved sodium silicate.
Described active constituent B is aluminum stearate.
Described quartz sand fineness modulus is 1.28-0.7.
Described water reducer is the naphthalene water reducer that sodium sulphate content is less than 3%.
During construction, by said components: the proportions slurry of water=1:0.4, during configuration slurry, order of addition(of ingredients) is: added in container by powder, then added by water while stirring, then mix uniform material with hand-held stirrer, churning time is about 3-5min.
Beneficial effect of the present invention is: 1. by the screening to cement raw material, effectively raise the intensity of material; 2. by adding the naphthalene water reducer that sodium sulphate content is less than 3%, improve degree of mobilization, reducing water consumption about 20%, effectively prevent material contracts cracking; 3., by adding quartz sand, calcium hydroxide and silicon ash, effectively raise degree of mobilization and the intensity of material; 4. by adding quick dissolved sodium silicate, aluminum stearate, sugared calcium retardant, achieve the controllability of condensation of materials time, in the presence of water, continuous generation penetrant crystalline reaction, form water-fast xln, block capillary channel, thus improve the degree of compactness of matrix, the impermeability of matrix is improved, effectively prevents various water to the erosion of buildings.The present invention, compared with traditional water-proof material, has respond well, premium properties such as construction simple, low to environmental requirement, good water resistance and weather resistance etc.
