Production method of cast-in-place light aggregate concrete

Abstract

The invention discloses a production method of cast-in-place light aggregate concrete, comprising the steps of preparing materials, including, by weight, 120-170 parts of cement, 40-70 parts of wasteceramic tiles, 5-10 parts of grinding wheel dust, 15-20 parts of mineral powder, 5-10 parts of sand, 1-5 parts of waste propylene fiber, 1-2 parts of a thickening agent, and 250-300 parts of water; heating the waste ceramic tiles, the grinding wheel dust and the mineral powder to 430-450 DEG C, and stirring for 5-8 min; adding the cooled mixture, the waste propylene fiber and half of the water into a stirring cylinder, and mixing for 10-15 min; adding the cement, the sand, the thickening agent and the rest water into the stirring cylinder, and mixing for 10-20 min; transporting the mixed concrete to a site or a prefabrication workshop for casting. The production method is scientific; the materials are finely selected; the waste ceramic tiles, the grinding wheel dust and the mineral powderpenetrate one another to form fine aggregate after being heated, so that concrete strength is improved, and high bearing capacity is provided. The waste propylene fiber that is difficult to degrade isadded, so that the toughness is improved; the concrete is light in structural weight, low in cost and widely applicable.

Description

technical field [0001] The invention belongs to the field of concrete building materials, and in particular relates to a preparation method of cast-in-place lightweight aggregate concrete. 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 c...
