Experimental Study On The Mix Proportion Of Fly Ash Cement Based Foam Concrete

Foam concrete is first foaming agent solvent by mechanical stirring or by compressed air, the foaming agent solvent fully foaming, then do the foam liquid and aggregate the full uniform mixing, finally using artificial mixing or mechanical mixing, foaming agent and other concrete material mixed evenly, finally the mixture into prepared Abrasives manufacturing molding. After the maintenance of natural or artificial standard curing conditions, the formation of foam concrete. Foam concrete foaming agent, because of the existence of the structure, there are a lot of pores, and eventually formed a new lightweight thermal insulation material. The materials in accordance with the environmental protection material concept. This paper uses a conventional preparation method of foam, compressive strength after mold maintenance measured seven days, twenty-eight days.Foam concrete is a new kind of energy saving and environmental protection type of lightweight concrete, has many excellent characteristics, such as insulation insulation performance is good, can be made of insulation materials; compared the quality of light can be filled enclosure material; seismic performance. Including the use of raw materials in this experiment:sand, foaming agent, fly ash, cement. For ordinary tap water, foam protein foaming agent, fly ash the fineness of fly ash on the Huainan local Pingwei Power Plant is 45 m, cement for Anhui Province Huainan Bagongshan brand, the strength grade of 42.5mpa high strength of ordinary portland cement, sand for sand production in the region.The Chinese government vigorously promote green energy-saving new materials, environmental protection materials, foam concrete is undoubtedly our construction industry a kind of energy saving and environmental protection materials, very much in line with the government’s policy. Therefore vigorously promote and Study on foam concrete has good prospects for the study.The foaming agent, sand, fly ash, cement and water as basic raw materials in this experiment, made of lightweight foam concrete. Before the experiments have the basic train of thought to develop down, in this study the first consideration, under the influence of single factor, namely the mixing amount of the fly ash water material ratio of 30%,40%,50% under their respective on the strength of foamed concrete effect; at the same time, the bubble mixed influence factors of coagulation Tu strength also includes:water cement ratio, fly ash, sand content, so the club by way of orthogonal test, to consider the influence of multiple factors on the strength of foamed concrete. Finally, this paper measured the during the curing period for 7,28 world, dry density and strength and the influence due to the relationship between the elements.
