Coal ash foam building block production method

Abstract

The invention provides a coal ash foam building block production method. According to a formula, a dry blend is composed of coal ash, blast furnace slag, gypsum powder, perlite and cement, and polystyrene particles, water and various additives are added in each ton of dry blend. A production system is composed of hoppers, stock bins, a polystyrene particle puffing machine, electronic scales, an auger conveyor, a water pump, a stirring machine, mold trolleys, a light rail and a bin for the various additives. The production system is characterized in that the electronic scales which are controlled by a computer are installed at outlets of the stock bins correspondingly and are in butt joint with the auger conveyor, the auger conveyor is connected with the feeding end of the stirring machine, and an outlet of a polystyrene particle bin is connected with the stirring machine; the puffing machine is connected with a steam pipe; the stirring machine is connected with a water pump water outlet pipe; the mold trolleys are arranged on the light rail, and mold assemblies are arranged on the mold trolley and are in butt joint with an outlet of the stirring machine; and wet blends are poured into molds for formation, manual demolding is conducted, and water is poured for curing. According to the coal ash foam building block production method, waste can be changed into valuable materials, the formula is nontoxic and free of odor and radioactive contamination, and coal ash foam building blocks produced through the method are pure-natural, green, healthy, ecological and environment-friendly wall materials.

Description

technical field [0001] The invention relates to a production method of a fly ash foam block, which belongs to the technical field of building materials. Background technique [0002] The partition walls of high-rise buildings are hand-built with materials such as red bricks, cement bricks, and lighter foamed bricks. After several times of plastering and leveling, it is very laborious, expensive, and long-term. , The design of building mechanics is expensive, the amount of steel is large, and the wet construction is not environmentally friendly. Contents of the invention [0003] The problem to be solved by the present invention is to provide a method for producing fly ash foam blocks. [0004] In order to solve the above technical problems, a kind of fly ash foam block production method provided by the present invention, the raw material formula comprises: fly ash: 10-15%, blast furnace slag 10-15%, gypsum powder 8-10%, pearl Rock 10-15%, 425# cement 45-50% constitute dr...
