Abstract
The invention discloses a kind of early-strength gypsum base thick-layer leveling mortar, the mass percent of leveling mortar component is as follows：Gypsum, 10 40%；Hydraulic cementing materials, 0 10%；Exciting agent, 0 5%；Filler, 40 80.75%；Additive, 0.25 5%；The additive is redispersable latex powder, super plasticizer, water-retaining agent, retarder, segregation reducing agent, antifoaming agent, and the mass percent of component is respectively：Redispersable latex powder 0 3%；Super plasticizer 0.05 0.5%；Water-retaining agent 0 0.2%；Retarder 0.05 0.2%；Segregation reducing agent 0 0.1%；Antifoaming agent 0.01 0.2%.It is uniformly mixed by the mass percent of said components and is packaged into bag.This product has the advantages that early strong, ungauged regions, wear-resisting, water-fast, application property is good, anti-isolation bleeding, low cost and without harmful chemical.
Description
Technical field
The present invention relates to a kind of leveling mortar, specifically a kind of early-strength gypsum base thick-layer leveling mortar.
Background technology
Gypsum base thick-layer leveling mortar is by gypsum, hydraulic cementing materials, exciting agent, priority with gathering materials and additive
A kind of pulverulent material made of factory's premixing in appropriate proportions.Used time need to only add water stirring can become uniformly, consistency it is suitable,
The early-strength gypsum base thick-layer leveling mortar with self-leveling of construction requirement can be met.
At present in engineering common leveling mortar with cement base facing sand slurry based on, and cement base facing sand slurry there are intensity
The problems such as development is slow, and fluidity is poor, surface powder, hollowing easy to crack, it is unstable to directly result in construction quality, and building is not achieved and sets
Meter standard；In addition, although gypsum base leveling mortar contraction is relatively low, due to its water resistance, wearability, the shortcomings of bleeding is easily isolated not
It is used widely.
Invention content
