Portland cement and preparation method thereof

Abstract

The invention discloses Portland cement and a preparation method thereof. The Portland cement comprises the following raw materials in parts by weight: 50-60 parts of Portland cement clinker, 10-15 parts of graphite polyphenyl granules, 5-6 parts of limestone, 7-10 parts of kapok fibers, 4-6 parts of gypsum powder, 1-3 parts of silicon dioxide, 1.5-2 parts of a foaming agent and 35-45 parts of water. The preparation method comprises the following steps of: mixing and grinding Portland cement clinker, graphite polyphenyl granules, limestone and kapok fibers to obtain a mixture A, then adding the mixture A and water into a high-speed stirrer for secondary mixing to obtain a mixture B, then adding the mixture B, gypsum powder and silicon dioxide into a mixing stirrer for mixing to obtain a mixture C, and finally adding the mixture C and a foaming agent into a mixing stirrer for mixing. According to the Portland cement and the preparation method thereof, the graphite polyphenyl granules, the kapok fibers and the foaming agent are added, so that the Portland cement has the effects of efficient isolation and convenient heat preservation, and the Portland cement is relatively low in production cost, simple and rapid in process and suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of Portland cement, in particular to a Portland cement and a preparation method thereof. Background technique [0002] Cement is a powdery hydraulic inorganic gelling material, which forms a slurry after being stirred with water, and can be hardened in the air or better hardened in water, and can firmly bond sand, stone and other materials together. Important cementing material, widely used in civil construction, water conservancy, national defense and other projects. Among them, Portland cement is made by mixing Portland cement clinker, mixed materials, and the like. [0003] At present, the sound insulation effect of Portland cement on the market is poor, and the thermal insulation effect is not obvious. Moreover, some Portland cement has a high production cost, which has gradually failed to meet people's needs. [0004] Aiming at the problems in the related technologies, no effective solution has been proposed ye...
