preparation example Construction

[0008] Preparation of concrete: mix cement, water, sand and stone according to JGJ55-2000 ordinary concrete ratio, namely: cement 329kg / m 3 , water 122.5kg / m 3 , sand 705.24 kg / m 3 , stone 1339.26 kg / m 3 . Concrete was prepared according to the above proportions.

[0009] The embodiment of the preparation of the cement prefabricated block with waste polystyrene foam and superabsorbent resin as filler is as follows:

Embodiment 1

[0010] Example 1: Mix the prepared concrete with waste polystyrene foam at a volume ratio of 3:1, then add super absorbent resin at a mass ratio of 1:320 to the concrete prepared above, mix evenly, shape and maintain , that is, a cement prefabricated block filled with waste polystyrene foam and superabsorbent resin.

Embodiment 2

[0011] Example 2: Mix the prepared concrete with waste polystyrene foam at a volume ratio of 4:1, then add superabsorbent resin at a mass ratio of 1:320 to the concrete prepared above, mix evenly, shape and maintain , that is, a cement prefabricated block filled with waste polystyrene foam and superabsorbent resin.

Abstract

The invention discloses a preparation method of a prefabricated cement block taking waste polystyrene foam and super-absorbent resin as filler. The preparation method comprises the main process flows of: proportioning cement, water, sand and gravel according to ordinary concrete JGJ55-2000 so as to prepare concrete; and mixing the prepared concrete with the waste polystyrene foam according to a certain volume ratio, adding the super-absorbent resin of certain mass, uniformly mixing, shaping and curing, thereby obtaining the prefabricated cement block which takes the waste polystyrene foam and the super-absorbent resin as the filler. The prefabricated cement block prepared by the method has the advantages of light weight and heat and sound insulation, and is expected to play a significant role in the field of construction.

Description

technical field [0001] The invention relates to a method for preparing a prefabricated block that can be used in construction, in particular to a method for preparing a cement prefabricated block by using cement, sand, waste polystyrene foam and superabsorbent resin as main raw materials. Background technique [0002] The present invention is mainly aimed at the serious environmental pollution caused by the current polystyrene foam which has not been rationally utilized, and at the same time, the demand for light-weight and heat-retaining building materials in the construction field increases rapidly. The use of waste polystyrene foam as the filler of cement prefabricated blocks can reduce the environmental pollution caused by waste polystyrene foam. At the same time, the water absorption and swelling of superabsorbent resin can occupy a certain space, and can form vacancies after water loss, and can moisturize after water absorption. . In this way, a new type of cement pre...
