Example Embodiment

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments.

[0019] refer to figure 1 , a preparation method of light mortar for ground cushion, comprising the following steps:

[0020] S1: Preparation of cement mortar: Weigh the raw material cement, sand and some admixtures. The admixtures are put into renewable dispersible latex powder, and the above-mentioned raw materials are put into the conical twin-screw mixer according to the ratio of 3:9:1 and stirred evenly , the stirring time is 20-35 minutes, and the cement mortar is obtained after stirring;

[0021] S2: Lightweight aggregate and admixture filling: Prepare light-weight mortar raw materials and mix cement according to the ratio of 25-30 p...

Abstract

The invention discloses a preparation method of light-weight mortar for a ground pad layerfloor cushion. The method comprises the following steps of preparing cement mortar; weighing raw material including cement, sand and partial part of additives; adding renewableregeneratable latex powder as the additives; adding the raw materials into a conical double spiral stirring machine to be uniformly stirred according to the mixture ratio of 39:1 for the stirring time of 20 to 35 minutes; after the stirring, obtaining the cement mortar; filling charging light aggregate and additives; preparing the light-weight mortar raw materials according to the proportion ratios of 25 to 30 parts of light aggregates, 15 to 25 parts of polymer modified fillers and 5 to 10 parts of renewable dispersible latex powder; mixing the cement mortar; combining the aggregates according to the mixture ratio, wherein the light aggregates compriseinclude man-made light aggregate clay ceramsitesceramicites, natural light aggregate pumice stone and industrial waste material fly ash ceramsitesceramicites. The light-weight mortar has the characteristic of light weight. The light-weight aggregates comprise the man-madelight aggregate clay ceramicitesceramisites, the natural light aggregate pumice stone and the industrial waste material fly ash ceramicitesceramisites. T, so that the self weight of the building and the burden on the basic load can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of ground cushions, in particular to a preparation method of lightweight mortar for ground cushions. Background technique [0002] Lightweight mortar for ground cushion is composed of uniformly mixed mortar powder and light aggregate. Generally, it is used in the form of two components, that is, mortar powder and light aggregate are produced separately in professional manufacturers, and after being transported to the construction site, they are used after mixing with water according to the specified proportion at the place of use. The clearance area between the main indoor walls is multiplied by the design thickness to calculate the volume, and the volume occupied by structures protruding from the ground, equipment foundations, indoor tunnels, trenches, holes with a single area of ​​more than 0.3 square meters, and independent columns should be deducted. The properties of the existing ground cushion prepara...
