A kind of heat preservation weakening light concrete, it is characterised in that:Raw materials by weight portion includes:130 parts of cement, flyash 70 Part, 20 parts of potassium hydroxide, 25 parts of miberal powder, 13 parts of polyacrylic fibres, ripe 11 parts of glutinous rice flour, 1 part of thickener, 320 parts of water.
As a modification of the present invention, the length of the polyacrylic fibres is 3-5cm, a diameter of 0.1-0.2mm.
A kind of preparation method for keeping the temperature weakening light concrete, includes the following steps:
(1)The water of cement, miberal powder, ripe glutinous rice flour and half is put into mix and stir and is mixed and stirred in cylinder 15-25 minutes;
(2)It adds in flyash, potassium hydroxide and remaining water to mix and stir 10-20 minutes, steam curing 30-40 minutes;
(3)Polyacrylic fibres and thickener are thrown into again and mixes and stirs cylinder and mix and stir 5-10 minutes;
(4)The light concrete of the uniform mixing scene of transporting or prefabricated workshop are poured into a mould.
The beneficial effects of the invention are as follows:
A kind of heat preservation weakening light concrete of the present invention, particular care is given to selecting the ingredients, and preparation method science, flyash is in steam curing condition Under, it is chemically reacted with potassium hydroxide, compound of the generation with hydraulic gelling property increases intensity and the heat preservation of concrete Property, the addition of ripe glutinous rice flour can agglomerate the constitutive material of lightweight concrete, enhance the effect of weakening, polypropylene can increase Toughness, bearing capacity of the present invention is strong, and structure is light, at low cost, is worthy to be popularized.
