Abstract

The invention discloses lightweight concrete with high shock absorption performance and a production process thereof. The lightweight concrete with high shock absorption performance comprises the following raw materials in parts by weight: 90-120 parts of cement, 60-80 parts of fly ash, 70-90 parts of ceramsite, 200-260 parts of fine bone, 5-9 parts of a water reducing agent, 2.8-4.2 parts of a synergist, 30 to 40 parts of styrene-butadiene latex, 20-30 parts of chloroprene rubber adhesive, and 60-70 parts of water. The design is novel, the CTF synergist, the LBD synergist and the water reducing agent are added into the concrete, inorganic insoluble particles in the concrete can be better dispersed, the styrene-butadiene latex can increase the viscosity of a stirred material and ensure the tensile resistance of the concrete after solidification, the added chloroprene rubber adhesive belongs to a synthetic rubber compound and is high in bonding strength, an elastic compounding capability is achieved after solidification, and the shock absorption performance of the concrete can be effectively improved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to lightweight concrete with strong shock absorption and a production process thereof. Background technique [0002] Lightweight concrete, also known as foam concrete, is to fully foam the foaming agent mechanically through the foaming system of the foaming machine, and mix the foam and cement slurry evenly, and then carry out cast-in-place construction through the pumping system of the foaming machine Or mold forming, a new type of lightweight thermal insulation material containing a large number of closed pores formed by natural curing. It belongs to the bubble-like thermal insulation material, and its prominent feature is that it forms closed foam pores inside the concrete, which makes the concrete lightweight and heat-insulating; it is also a special variety of aerated concrete, and its pore structure and material properties are close to those of the aerated concrete. For air-...
