Abstract
The invention belongs to the field of a formula of cement, and particularly relates to a formula for production of cement with fly ash of a power plant. The formula comprises the following materials in parts by weight: 40-55 parts of fly ash of a power plant, 20-25 parts of quicklime, 3-8 parts of anti-freezing agent, 3-8 parts of enhancer and 4-34 parts of enhancer. The formula has the beneficial effects that: the defects of poor rigidity, low stability, low hardness and the like of the existing formula for production of cement with fly ash of the power plant can be overcome, all indicators of cement produced according to the formula can meet relevant national standards, and the rigidity, stability, hardness and the like can be improved greatly.
Description
technical field:
The invention belongs to the formula field that produces cement, relate in particular to a kind of formula of producing cement with fly ash in electric power plant.
background technology:
Coal fired power generation is one of electrical production mode of generally adopting of various countries, and a large amount of flyash that produce for fire coal, effective utilization of bottom slag are world subjects.China is world's coal fired power generation the first big country, and generating and cogeneration every year consumes approximately 5.35 hundred million tons, raw coal, and the flyash of discharge reaches 1.8 hundred million tons, because current utilization ratio is less than 30%, a large amount of flyash have become industrial refuse, have not only polluted environment, and have taken a large amount of soils and stack.By the domestic and international long-term research and practice to utilization of fly ash, find to utilize flyash to produce building material, there is the features such as lightweight, high-strength, insulation, can replace clay brick and shale brick completely, and this technology maturation is feasible.By the application of this technology, not only make flyash be effectively used, pollution abatement, reduces land seizure, and, by reducing the production of clay brick and shale brick, will make to produce destroyed a large amount of soils because of clay brick every year and be protected.
CN01144914.4 discloses a kind of method of Power Plant Ash cinder production standard brick, the liquid slag and the pulverized fuel ash as raw materials production standard brick that utilize in the method boiler of power plant to discharge, brick Functionality, quality and appealing design, the cost produced are low, and indices has all reached the requirement of relative national standards.
CN01144913.6 discloses a kind of by plant residue ash masonry and coating mortar method processed, and the liquid slag and the flyash that utilize in the method boiler of power plant to discharge, add a certain amount of cement clinker and toughener to produce block and smear mortar.The method is not only recycled fly ash in electric power plant, and the mortar of producing has reached relative national standards.
At present, relevant fly ash in electric power plant is done the research of building materials, and each investigator has made extensive work, has also obtained some achievements.But it is little that power plant utilizes flyash to produce the report of cement, is rich in the needed compositions of cement such as silicon oxide, aluminum oxide, ferric oxide in fly ash in electric power plant, is a route that has potentiality so utilize flyash to produce cement.But the cement that utilizes on the market flyash to produce all exists some shortcomings, such as poor rigidity, stability are low etc., so research and develop a kind of Novel coal ash, to produce the formula of cement be trend of the times.
summary of the invention:
The object of the invention is to produce in order to overcome existing fly ash in electric power plant the existing poor rigidity of formula of cement, the shortcoming such as stability is low, hardness is little, and a kind of new formulation of development.The indices of the cement that this formula is produced has all reached relative national standards, and has also obtained large increase at aspects such as rigidity, stability, hardness.
Technical scheme of the present invention: flyash of the present invention is produced the formula of cement, is made up of following component by weight:
Fly ash in electric power plant 40-55 part; Unslaked lime 20-25 part; Frostproofer 3-8 part; Toughener 3-8 part; Accelerating chemicals 4-34 part.
Above-mentioned frostproofer is mainly: the combination of any one in Sodium Nitrite, sodium-chlor, sodium lignosulfonate, SODIUMNITRATE or two or more any mass ratio.
Above-mentioned toughener is mainly: calcium, aluminium, silicon particle, one, the mixture of bivalent metallic compound, alcohol type organic, interfacial agent.
Above-mentioned one, bivalent metallic compound is iron protoxide, zinc oxide, nickel oxide, magnesium oxide.
Above-mentioned accelerating chemicals is mainly: the combination of any one in aluminate, sodium carbonate, water glass or two or more any mass ratioes.
The invention has the beneficial effects as follows: the indices that overcomes the cement of the shortcomings such as existing fly ash in electric power plant is produced the existing poor rigidity of formula of cement, stability is low, hardness is little and the production of this formula has all reached relative national standards, and has also obtained large increase at aspects such as rigidity, stability, hardness.
