Heat preservation oscillation damping light concrete and preparation method thereof

Abstract

The invention discloses heat preservation oscillation damping light concrete. The concrete is prepared from, by weight, 110-140 parts of cement, 40-90 parts of coal ash, 10-30 parts of potassium hydroxide, 20-30 parts of mineral powder, 10-15 parts of polypropylene granules, 5-15 parts of cooked glutinous rice powder, 0.5-2 parts of thickener and 300-350 parts of water. The materials are selectedfinely, the preparation method is scientific, the coal ash and the potassium hydroxide are subjected to a chemical reaction under the steam curing condition, a compound with the water hardening gelling property is generated, the temperature of the concrete is increased, the heat preservation property of the concrete is improved, by adding the cooked glutinous rice powder, the raw materials of thelight concrete can be condensated, the oscillation damping effect is enhanced, tenacity can be improved due to polypropylene, and the concrete is high in bearing capacity, light in structure, low in cost and worthy of being popularized.

Description

technical field [0001] The invention belongs to the field of concrete building materials, and in particular relates to a heat-preserving and vibration-absorbing lightweight concrete and a preparation method thereof. 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 ...
