Abstract
The invention belongs to the technical field of building materials, particularly relates to a cement base self-leveling for a cushion layer, which is obtained by using cement as a main gelatinization material to be mixed with admixture such as superplasticizer and stabilizing agents, fine sands, fine packing and the like, by weight, 25-35 parts of cement, 5-10 parts of swelling agent, 45-55 parts of aggregate, 11-16 parts of fine materials, 0.2-0.3 part of plasticizing agent, 0.2-0.3 part of antifoaming agents, 0.05-0.2 part of stabilizing agent, 1.5-3 parts of emulsion powder, 0.4-0.9 part of retarder and 0.1-0.4 part of coagulation accelerator. The cement base self-leveling solves the problem that a large block of construction is cracked caused by poor after-contraction performance, and has the waterproof function.
Description
Technical field:
The invention belongs to building material technical field, a kind of specifically bed course is used cement-based self-leveling.
Background technology:
At present, cement-based self-leveling ground mortar is meant that with cement be main gelling material, with the building ground alignment material that admixtures such as superplasticizer, stablizer and fine sand, flour filler etc. mix, is a kind of of dry-mixed mortar.
Since the eighties in 20th century, developed countries such as the U.S., France, Germany, Italy, Sweden, Finland, research and development have been produced ground and have been used gravity flowing levelling mortar in succession, and have obtained being widely used.Product category comprises cement based, gypsum base, magnesite base, asphaltic base and 5 kinds of earth materials such as synthetic resin based, but produce, still cement-based self-leveling mortar that use face is wider.
In China, ground self-leveling mortar is a kind of new terrestrial material, is particularly useful for industrial premises and layer is leveled up on ground, house decoration room.The construction thickness of auto-flowing floor mortar is generally 3-10mm, can be according to the thickness of requirement of client adjustment gravity flow flat bed.This material have good leveling property, early strength high, characteristics such as be easy to lay, speed of application is fast, the duration is short, be a kind of have carry and decorate dual-use function, and the building material product had an optimistic view of of development prospect.
Yet existing cement-based self-leveling mortar also has some shortcomings:
1) follow owing to substrate surface is inconsistent in levelling that crackle might appear in the reason of drying shrinkage behind the hydrated cementitious, chap, come off, the phenomenon of hollowing.
2) when cement-based self-leveling does not possess water-proof function, after suffering water erosion and influence of temperature variation, the disease that also occurs ardent, seepage, hollowing easily and come off from levelling.
Summary of the invention:
The present invention does not solve because the later stage shrinkage is good and causes bulk construction rimose problem, and has water-proof function.
The present invention provides a kind of cement based bed course from levelling, and the weight percent of each material component is following:
Cement 25%～35%
Aggregate 45%～55%
Fines 11%～16%
Superplasticizer 0.2%～0.3%
Skimmer 0.2%～0.3%
Stablizer 0.05%～0.2%
Latex powder 1.5%～3%
Retardant 0.4%～0.9%
Setting accelerator 0.1%～0.4%
Said cement is common 42.5 silicate cements and high-alumina cement synthetic complex cement, and the two weight ratio is 100: 10～30.
Said aggregate is particle diameter 40～70 orders and 70～140 purposes washing river sand, and weight ratio 100～50: 50～100 is composite.
Said fines is that anhydrite follows water-ground limestone composite, and the two weight ratio is 100: 300～450.
Said superplasticizer is a modified polycarboxylic acid ether.
Said skimmer is the mixture of liquid hydrocarbon, polyoxyethylene glycol and amorphism silicon.
Said latex powder is the ethylene copolymer rubber powder.
Said retardant is a Trisodium Citrate.
Said setting accelerator is a Quilonum Retard.
Said stablizer is the non-association type high-molecular copolymer of synthetic.
