Preparation method of high-strength concrete separation wall

Abstract

The invention discloses a preparation method of a high-strength concrete separation wall. The method includes the steps: raw material preparation: by weight, 120-200 parts of cement, 40-70 parts of slag, 6-15 parts of PPR powder, 3-7 parts of grinding wheel ash, 5-10 parts of sand, 1-2 parts of thickening agents and 250-300 parts of water; heating the slag, the PPR powder and the grinding wheel ash to reach the temperature of 130-150 DEG C, and stirring mixture for 15-25 minutes; adding the mixture, the thickening agents and half of the water into a blending cylinder to blend mixture for 10-20minutes; adding the cement, the sand and the rest water into the blending cylinder to blend mixture for 15-20 minutes; transporting the uniformly blended concrete to a field or prefabricating workshop to perform pouring. The preparation method is scientific, raw materials are finely selected, the slag, the PPR powder and the grinding wheel ash are heated and then mutually permeate to form fine aggregates, toughness is increased when strength is increased, and the separation wall is high in bearing capacity, simple in structure, low in cost and wide in application range.

Description

technical field [0001] The invention belongs to the field of concrete building materials, and in particular relates to a preparation method of a high-strength concrete partition wall. Background technique [0002] In the past, civil buildings in my country have always been dominated by brick-concrete structures. The brick-concrete structure uses a huge amount of bricks, uses up a lot of soil for farming, and the process of firing clay bricks consumes a lot of energy, which has a negative impact on the environment. In addition, solid clay bricks have poor thermal insulation performance, which greatly increases the annual heating energy consumption. With the continuous development and progress of society, the development direction of building modernization is low cost, heat preservation, earthquake resistance, and long service life. The frequently used lightweight concrete has its application fields in construction projects expanding due to its good characteristics, and can be...
