[0002] As the ground leveling mortar for the bottom leveling treatment of light floor decoration materials such as existing wooden floors, its components and weight ratio are usually 40-50 cement, 20-30 quartz sand, and 10-20 coarse sand. The specific gravity of the mortar is 1700-1800Kg / m 3 , The proportion is large, which not only increases the load of the building, but also has many consumables and heavy vertical transportation burden, and also causes the mortar machine to block the pump, pipe, and gun, hindering the smooth progress of mechanized construction, low construction efficiency, and poor self-leveling performance. Poor horizontality, it is difficult to achieve the effect of one-time rapid prototyping (reaching the required thickness)

Embodiment 1
[0035] Take each component according to the weight shown in Example 1 in Table 1. The production process: mix ordinary Portland cement, slaked lime, light aggregate, heavy aggregate and compound additives, and stir them evenly with a machine to obtain this example. 1 Indoor use of lightweight ground leveling mortar, packed in paper bags or in bulk.
[0036] Construction method: Dilute 100 kg of the lightweight ground leveling mortar obtained in Example 1 with 30 kg of water, stir mechanically or manually until the mixture is uniform, and reach the experience viscosity suitable for mechanical spraying or manual construction, then mechanized spraying or manual work can be carried out.
[0037] The performance testing results are shown in the corresponding data of Example 1 in Table 2, wherein the testing basis for dry surface density is GB / T 20473-2006, the testing basis for thermal conductivity is GB / T 102951988, the compressive strength and drying shrinkage value The testing b...

Abstract
The invention relates to a light-weight indoor floor leveling mortar, which comprises the following components in proportion by weight: 30-35 ordinary portland cement, 4-5 hydrated lime, 5-8 light aggregate, 55-60 heavy aggregate (ordinary river sand) and 1.0 compound additive, wherein the light aggregate is an inorganic vitrified hollow cellular material of which the fineness is lower than 100 meshes; and the compound additive can be prepared by mixing 0.1 part by weight of dispersible latex powder, 0.3 part by weight of cellulose ether, 0.5 part by weight of water reducing agent and 0.1 part by weight of coagulant agent. The construction method comprises the following steps: watering the mortar with water which is 30-50% of the mortar in weight, mechanically or manually mixing until themortar and water are evenly mixed and achieve the viscosity, and carrying out mechanical spray coating or manual construction. The mortar of the invention has light weight, self-leveling performance,good smoothness, easy toweling, rapid construction, simple and practical process, low cost of unit area and popularization value, is favorable to mechanized construction, lightens the load quantity of a building body, improves the safety earthquake-resistant performance of the construction, achieves leveling thickness rapidly once, and is very suitable for leveling the floor of the bottom surfaceof a light weight floor material, such as a wood floor and the like.
