利用复合添加剂研制免烧免蒸粉煤灰砖

论述了利用复合添加剂生产免烧免蒸粉煤灰砖的制造技术，并采用模糊数学和正交试验法求出最佳工艺参数。试验表明该项新技术生产的粉煤灰砖具有强度大、抗冻性与耐水性好及成本低等优点。

Development of Non-fired and Non-stream-cured Brick of Fly Ash by Use of Compound Admixture

The producing principle and manufacturing technique of non-fired and non-Stream-cured bricks of fly ash by use of compound admixture were discussed. The optimum technical parame-ters were determined by fuss mathematics and orthogonal experiment. The text results show that the brick produced by use of the new technique offers many advantages such as high stregth,good anti-feezing ability and resistance of water and low cost.
