Have different effects on different varieties of fly ash raw strength of aerated concrete equipment products Different varieties of the different regions of the fly ash, different strength of aerated concrete equipment products, inspection of the physical properties of the local fly ash in the production of aerated concrete block plant investment is very necessary. According to the summary of the test data and other test work and trial experience, in order to ensure that the mechanical properties of fly ash bricks, fly ash quality should be mastered within a certain range, silica and alumina content in fly ash is not less than a total of 70% of the fineness of the fly ash in 4900 holes per square centimeter sieve sieve residue does not exceed 15%,Aerated Lightweight Brick Machine not more than 15% of the carbon content in the fly ash. The carbon content in the fly ash does not exceed 15%. Activity oxide content of aerated concrete block or fly ash brick strength strength of more 20mpa of fly ash, silica and alumina content of more than 70%, the intensity only 11mpa its powder ash silica-alumina content of only 53%, together with its high carbon content, low intensity inevitable. Also, the fineness of fly ash aerated concrete block strength also have a great impact, if the fly ash in silica-alumina content of up to 83.07%, and the compressive strength of only 16.8mpa, the reason is that the fly ash too thick, up to 55.5% in 4900 holes per square centimeter sieve sieve I test this gray ground it down to 15% to the sieve I aerated concrete block strength along to 29.3Mpa . Light Weight Block Machine Many proved, fly ash carbon content is below 15%, the carbon magnitude of aerated concrete block strength was less affected, so in the choice of aerated concrete block equipment Production should begin on raw materials the tests and analysis, exceeds 15%, the carbonaceous magnitude great influence, sometimes with a plant to the production of fly ash, but the activity of the two similar, because the difference of combustion conditions, combined with the different fineness the both strength almost doubled,Lightweight Concrete the carbon content of not more than 15%, a relatively small impact on the strength, when the carbon content is higher at 12.93% <15%, an appropriate increase in the fineness of 4900 holes per square centimeter, sieve residue 10.5 %, may be a better indicator of the strength.
