Abstract
The present invention relates to mixed diorite cement which is formed by together milling diorite, portland cement clinker and dihydrate gypsum, wherein the diorite is a mineral with low industrial value and is widely distributed in China. The cement produced by mixed diorite material has the advantages of good color, low cost, high economic benefit, etc., and has physical performance similar to that of ordinary portland cement and pozzolana portland cement. The new variety of the cement is added. The present invention widens the application range of mixed cement material, and can be widely applied to industry, agriculture and national defence engineering construction.
Description
The invention belongs to the manufacturing field of cement.
Be mixed with the portland-type cement of blended material, had bigger development in recent decades, enlarging cement type, improve cement performance, aspects such as reduction cement cost have played positive pushing effect.With industrial residue as: slag, flyash, coal gangue etc. are the cement of blended material and are the cement of blended material with natural mineral as the stone that stagnates, volcanic ash, Black Warrior stone etc., brought huge economic benefit for Cement industry, and be the cement of blended material with the diorite, be not reported so far both at home and abroad.
The objective of the invention is to develop new cement type, enlarge the range of application of blended material, improve the performance of cement, reduce the cost of cement, improve the business economic benefit.
Mixed diorite cement of the present invention is made by the common grinding of diorite, Portland clinker and gypsum.Its raw material is formed weight has partition ratio as follows:
Grog: 43～92%
Diorite: 5～50%
Gypsum: 3～7%
Require the grog label more than 50MPa, the grinding fineness standard of being controlled at tails over and is not more than 10%, or Blain specific surface is 3000 ± 100cm
2/ g, used gypsum are SO
2Natural dihydrate gypsum greater than 30%.
The cement that utilizes diorite to produce as blended material, color and luster is good, and cost is low.And have the physical and mechanical property similar with Portland pozzolana cement to ordinary Portland cement, can be widely used in industry, agricultural and defence engineering construction.The present invention has widened the range of application of cement mixture, for the development of cement has increased new variety.Because the diorite mineral are widely distributed, price is low, and need not dry, and can save a large amount of oven dry expense and fuel, so economic benefit is high.
Most preferred embodiment of the present invention:
Embodiment 1, and the weight percent proportioning is a Portland clinker 85%, diorite 10%, gypsum 5%;
Embodiment 2, and the weight percent proportioning is a Portland clinker 65%, diorite 30%, gypsum 5%.
Embodiment 1 and 2 parameters such as intensity see the following form:
