Hydrophobic polystyrene foamed concrete and preparation method thereof

Abstract

The invention provides hydrophobic polystyrene foamed concrete and a preparation method thereof and belongs to the technical field of building materials. Based on the volume capacity, the hydrophobicpolystyrene foamed concrete per cubic metre comprises 0.5-0.8m<3> of polystyrene granules, and the hydrophobic polystyrene foamed concrete comprises, by weight, 300-380 parts of cement, 0.8-1.2 partsof water repellent, 0.6-1 part of foamed concrete binding material foaming agent and 190-240 parts of water. The hydrophobic polystyrene foamed concrete has the advantages that the foamed concrete binding material foaming agent coordinated with the water repellent is used, and the foamed concrete binding material foaming agent is rich and fine and smooth in foam, low in water secretion quantity, long in foam stabilizing time and good in compatibility with a binding material; the foamed concrete which is a novel energy-saving building wall material product is lightweight, high in strength, lowin use amount, low in cost, good in water repelling performance, low in water absorption, resistant to fire, energy-saving, environmentally friendly and applicable to the pouring of thermal-insulationwalls.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a hydrophobic polystyrene foamed concrete and a preparation method thereof. Background technique [0002] Polystyrene foamed concrete is a kind that can achieve A 2 It is a building insulation material with the first-class fire protection standard. It is made of polystyrene foamed particles and foamed concrete. Fire insulation material with organic and inorganic double foam. [0003] Traditional polystyrene foamed concrete is non-hydrophobic, high water absorption, low foaming ratio, poor thermal insulation performance, high bleeding, and short foam stabilization time; due to the high water absorption of traditional polystyrene foamed concrete, resulting in Products made of traditional polystyrene foamed concrete are easy to crack, low in strength, easy to collapse, and poor in durability, which greatly affects the thermal insulation performance and market applicatio...
