One kind of concrete sludge and preparation method

The present invention discloses a method for preparing sludge and concrete, comprising cement, water, stone, fly ash, slag, sand and additives, further comprising a sludge, the sludge filtered by the extraction of natural inland Jiang He stacked obtained sludge the fineness of between 0.4 and 0.6, the fly ash grade ⅱ, the admixture for high performance enhancer. The mass fraction of the components as follows: 200-296 parts of cement, 172-180 parts of water, gravel 1030-1066 parts, 56-75 parts of fly ash, slag parts 40-78, 530-680 parts sand, plus agent 4.1-6.5 parts, parts 150-180 sludge. The present invention employs an alternative sludge sand as fine aggregate portion, and increases the compactness of the concrete barrier properties, improved durability of concrete, reducing production costs, has a large value and marketing prospect.
