Abstract

The invention relates to a method for the cast-in-place preparation of foamed concrete by comprehensively utilizing waste wood flour. According to the method, ordinary silicate cement, fly ash, the waste wood flour and a composite foaming agent are taken as main raw materials and can be prepared into autoclaved-free foamed concrete which can be applied to the cast-in-place of overall board rooms through admixtures. The method has the advantages that the problem that foamed concrete easily has mold collapse, cracking and the like during wall cast-in-place is solved; and self-heat-insulation foamed concrete with higher strength and crack-preventing and anti-penetrating functions is prepared and can be applied to the overall cast-in-place of building walls with the functions of load bearing or non-load bearing and heat insulation.

Description

A kind of cast-in-place method of preparing foamed concrete of waste wood powder that fully utilizes
Technical field
The present invention relates to a kind of preparation method of foamed concrete, relate in particular to a kind of cast-in-place method of preparing foamed concrete of waste wood powder that fully utilizes.
technical background:
Along with modern architecture floor is more and more higher, people are also more and more higher to the requirement of materials for wall, material of construction more trends towards to energy-saving, environment-friendly type, the development of light weight type aspect, with ordinary Portland cement, flyash, waste wood powder, composite foamable agent is main raw material, prepare the non-evaporating pressure foamed concrete that can be used for cast-in-place integral board house by admixture, obtain people's extensive attention, employing has chemical reactivity suds-stabilizing agent strengthening gelling material, assemble coupling between material and admixture, increase waste wood powder, doping quantity of fly ash is to reduce costs, solve the mould that easily collapses that foamed concrete occurs in cast-in-situ wall, problems of crack, it is the major subjects that people extensively conduct a research at present.
Summary of the invention
The object of this invention is to provide a kind of cast-in-place method of preparing foamed concrete of waste wood powder that fully utilizes, the foamed concrete that the method makes has higher-strength and has the function of waterproofing and anti-leakage self-heat conserving, by adjusting its density and intensity, can be used for entirety collection load-bearing or nonweight-bearing heat-insulating integral construction material.
The object of the present invention is achieved like this, it is made up of the raw material of following parts by weight: ordinary Portland cement 400~600kg, flyash 150~300kg, waste wood powder 50~100kg, water reducer 0.1~0. 2 kg, accelerating chemicals 4~10 kg, water 300kg, composite foamable agent 1000~1500mL.Its production method step is: 1) powder is mixed: after starting stirrer, ordinary Portland cement, flyash, waste wood powder, water reducer, accelerating chemicals are added respectively, pack stirs; 2) composite foamable agent foam-in-place: composite foamable agent adopts following proportioning raw materials to make: whipping agent mother liquor (whipping agent mother liquor is protein type) 30~60 ml, trolamine 0.1~0.3ml, sodium alkyl benzene sulfonate 0.2~0.6g, sesbania gum powder 0.3~0.8g that concentration is 20%, above-mentioned raw materials is produced composite foamable agent foam through foaming machine; 3) cast-in-site: add water to stir the powder mixing on request, then add composite foamable agent foam to stir to get final product casting.
