A kind of glass fiber reinforced cement and preparation method thereof

Abstract

The invention discloses fiberglass-reinforced cement, made from, by weight: 40-50 parts of cement clinker, 5-10 parts of alkali-resistant fiberglass, 1-5 parts of mineral residue, 1-5 parts of pulverized coal residue, 5-10 parts of limestone powder, 1-5 parts of sodium methyl silicate, 1-5 parts of anionic polyacrylamide, 1-5 parts of sodium methyl silicate, and 1-5 parts of acrylic emulsion; the alkali-resistant fiberglass is 5-15 Mum in diameter and 15-30 mm in length and includes the chemical components: 60-65% of SiO2, 15-20% of Na2O, 4.0-5.0% of Al2O3, 5-10% of ZrO2, 4.0-5.0% of CaO, 5-8% of B2O3, and 0-0.7% of BaO. The invention also discloses a preparation method of the fiberglass-reinforced cement, including: subjecting the cement clinker, mineral residue, pulverized coal residue and limestone powder to mixing, crushing and calcining to obtain semi-finished cement, and adding water and the remaining materials sequentially, stirring, drying, and crushing to obtain the finished cement. The fiberglass-reinforced cement prepared herein has the advantages of high strength, alkali resistance and water resistance, and is widely applicable to the severe environments such as alkaline environments and low-temperature environments, and the cement market is widened.

Description

technical field [0001] The invention relates to a cement and a preparation method thereof, in particular to a glass fiber reinforced cement and a preparation method thereof, and belongs to the field of building materials. Background technique [0002] Cement is a powdery hydraulic inorganic gelling material, which can be mixed with water to form a slurry, which can be hardened in the air or better hardened in water, and can firmly bind sand, stone and other materials together. Cement is one of the three basic materials in the construction industry. It is widely used and used in large quantities. It is known as "the grain of the construction industry". Although the production of cement requires more energy, the concrete made of cement, sand, stone and other aggregates It is a low energy consumption building material. Mortar or concrete made of cement is strong and durable, and is widely used in civil engineering, water conservancy, national defense and other projects. [00...

AI Technical Summary

Problems solved by technology

The above two patents use glass fiber to reinforce cement to improve the strength and toughness of cement. However, there is no further discussion on the composition of glass fiber. Fibers of different components are added to cement, which plays a key role in affecting its performance.
