Embodiment Construction

[0013] This specific embodiment adopts the following technical scheme: it contains 70% to 72% of phosphorus slag, 18 to 23% of fly ash, 6 to 19% of cement, the weight ratio of water to material is 0.33 to 0.43, and the alkali activator accounts for the cementitious material. The total weight is 3.6-4.3%, the air-generating agent accounts for 0.2-0.3% of the total weight of the cementitious material, the water glass slurry accounts for 1-3% of the total weight of the cementitious material, and the total amount of straw is 0.1-0.5%.

[0014] First, mix phosphorus slag, fly ash, cement and water according to the ratio, add alkali activator and stir for 5-10 minutes, add gas-generating agent and stir for 1-5 minutes, put into mold, shape, cut, and remove the mold after reaching the strength of mold removal , carry out natural maintenance, and make products.

[0015] In this specific embodiment, the alkali activator and the water glass slurry can assist in increasing the strength o...

Abstract

The invention discloses a formula for enhancing concrete strength and relates to the technical field of building materials. The formula comprises 70-72% of phosphorus slag, 18-23% of fly ash and 6-19% of cement; and the water-material weight ratio is 0.33-0.43, an alkaline activator accounts for 3.6-4.3% of the total weight of a cementing material, a gas foaming agent accounts for 0.2-0.3% of the total weight of the cementing material, water glass slurry accounts for 1-3% of the total weight of the cementing material, and the total amount of straw is 0.1-0.5%. The concrete strength is greatly enhanced, the application range of the concrete is expanded, the utilization rate of the concrete is increased, the preparation cost is low, and the concrete is nontoxic and harmless and has high safety coefficient and good groutability.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a formula for enhancing the strength of concrete doped with biomass. Background technique [0002] Concrete, also known as concrete, is one of the most important civil engineering materials in contemporary times. It is an artificial stone made of cementing material, aggregate and water prepared in a certain proportion, stirred and vibrated, and cured under certain conditions. Concrete has the characteristics of abundant raw materials, low price, and simple production process, so its usage is increasing; at the same time, concrete also has high compressive strength, good durability, and a wide range of strength levels, making it widely used, not only It is used in various civil engineering, that is, shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete is also an important material. [0003] The concrete pump consists of a pump bo...
