Abstract
The invention discloses a high-impermeability waterproof mortar. The high-impermeability waterproof mortar is mixed from the following components: cement, quartz sand, quartz sand, mineral waste residues, cellulose ether, a water repellent and a water reducer. The high-impermeability waterproof mortar adopts sulfate aluminum cement which is high in early strength, so that the duration can be saved, and the cement has the characteristics of being high in strength, high in compactness and low in alkalinity; moreover, additives such as the cellulose ether, the water repellent and the water reducer are added, so that the mortar construction is more convenient, the interface compatibility between the sand and the binding materials is good, the viscosity is good and the bonding strength of the mortar is improved; fewer capillary voids are caused, the shrinking percentage is low, the compactness is good and the waterproof impermeability of the mortar is effectively improved.
Description
Technical field
The present invention relates to a kind of building mortar, be specifically related to a kind of high permeability resistant waterproof mortar.
Background technology
Waterproof mortar is a kind of polymer modification waterproof material, can be widely applied to the sealing of various waterproofing work, repairing work or engineering structure, corrosion-resistant coating etc.；Waterproof pressure-resistant degree is higher than traditional material, salt water resistance humidity corrosion, prevents concrete carbonization, is more suitable for coastwise city and uses；Strong with base material cohesive force, the active ingredient in slurry can penetrate into the pore in cement basal plane, micro-crack and produce chemical reaction, combines together with ground and forms the waterproof layer of one layer of compact crystallization.
Common waterproof mortar many employings conventional cement mortar on the market, it is a kind of rigid material, fragility is big, toughness is not enough, easily crack, thus anti-permeability performance is poor, impermeability is an important performance indexes of waterproof mortar and cement-based material durability, thus is necessary to be modified improving the anti-permeability performance of mortar to mortar.
Summary of the invention
Present invention aim at, it is provided that a kind of high permeability resistant, easy construction waterproof mortar, the technical solution adopted in the present invention is:
A kind of high permeability resistant waterproof mortar, it is characterised in that mixed by weight percentage by following components
Conjunction forms:
Cement 20-40 part
Quartz sand 40-50 part
Slag 10-20 part
Cellulose ether 0.5-1.5 part
Hydrophober 0.5-1.5 part
Water reducer 0.5-1.5 part.
One of preferably, described cement is sulfur aluminium salt cement.
One of preferably, described cellulose ether is that viscosity is at 5-10 ten thousand mpa.s hydroxypropyl methyl cellulose ether.
One of preferably, described hydrophober is polysiloxanes powder hydrophober.
The present invention provides the benefit that relative to prior art: the high permeability resistant waterproof mortar of the present invention, have employed sulphate aluminium cement, sulphate aluminium cement early strength is high, thus can save the duration, and this kind of cement also has the characteristics such as high-strength, high compactness and low alkalinity.Additionally also added, cellulose ether, hydrophober, the additive such as water reducer, mortar easy construction, between sand and Binder Materials, interface compatibility is good, and toughness is good, improves the adhesion strength of mortar.Capillary gap is few, and shrinkage factor is low, and compactness is effectively improved well mortar waterproof impervious characteristic.
