Abstract
The invention discloses a clay screening agent. The clay screening agent comprises the following materials in percentage by weight: 0-50% of silicate, 0-50% of phosphate, 1%-5% of sodium gluconate, 1%-5% of lauryl sodium sulfate and 10%-50% of water. The preparation method of the clay screening agent disclosed by the invention comprises the following steps of: (1), firstly, weighing the materials in the percentage by weight; and (2), then, mixing and stirring the materials to obtain the clay screening agent, wherein the stirring temperature is 20 DEG C-50 DEG C, the stirring speed is 50 revolutions / minute-500 revolutions / minute, and the stirring time is 10 minutes-30 minutes. The clay screening agent disclosed by the invention can be used for preferably adsorbing the clay in a concrete gravel material, so that the bad influences of the clay are screened, and therefore, the acting effect of a polycarboxylic acid water reducing agent is improved. The clay screening agent is wide in material resource, not needed to be synthesized by chemical reaction, simple in preparation method, remarkable in acting effect and suitable for large-scale industrial production.
Description
technical field [0001] The invention relates to the technical field of building materials, in particular to a clay shielding agent and a preparation method thereof. Background technique [0002] The volume of aggregate in concrete accounts for about 70% of the concrete volume, and the quality of aggregate has a very important impact on the performance of concrete. The particle size of clay particles is less than 5??m, and the particle size of silt and dust particles is 5~50??m. These extremely fine particle materials form a coating layer on the surface of the aggregate, which hinders the bonding of the aggregate and the cement stone, forming a weak The interface layer, which may appear as loose particle aggregates, especially mud blocks, forms a weak "air space" in the concrete, reducing the compactness of the concrete. [0003] In the concrete production process, the clay contained in the aggregate is inevitably mixed into the cementitious material system. With the increas...
