Abstract

The present invention discloses a Portland cement mixing admixture which includes hydroxyapatite, shell powder, and garbage incineration waste ash. The Portland cement mixing admixture can effectively extend Portland cement compressive strength, improve the cement hardness and improve the cement anti-sulphate corrosion ability, and has good water resistance and a high use value.

Description

A kind of mixing adulterant of silicate cement
Technical field
The present invention relates to technical field of cement production, particularly relate to a kind of mixing adulterant of silicate cement.
Background technology
For a long time, silicate cement is as a kind of important gelatinous material, and the consumption of ordinary Portland cement is very large, is widely used in construction work.But silicate cement also has some shortcomings, such as hydration heat is large, corrosion-resistant, poor heat resistance etc.
Along with the quickening of China's Development of China's Urbanization, being processed in order to a difficulties of municipal wastes.The main methods of current municipal wastes is burning disposal.Produce volume of smoke after waste incineration, do not give harmless treatment, secondary pollution can be caused to environment.The external multipair smoke dust produced that burns carries out filling up process.
In order to make up silicate cement these deficiencies qualitative, a kind of solution mixes two or more composite woods exactly in cement, can mutually learn from other's strong points to offset one's weaknesses, and overcomes the shortcoming of single mixed material cement.Add incineration of refuse flyash simultaneously, can turn waste into wealth, alleviate waste incineration causes secondary pollution pressure to urban environment.
Summary of the invention
For this reason, object provided by the invention is the mixing adulterant providing a kind of silicate cement.To solve silicate cement Problems existing
For achieving the above object, the mixing adulterant of described silicate cement, is made up of following raw material: hydroxyapatite, oyster shell whiting and the useless ash of waste incineration.
Alternatively, according to mixing adulterant of the present invention, the weight proportion of described raw material is: described hydroxyapatite proportioning is between 10% to 15% of total mass, and oyster shell whiting proportioning is between 5% to 7% of total mass, and waste incineration gives up grey proportioning between 5% to 10% of total mass.
Further, follow according to mixing adulterant of the present invention, described hydroxyapatite and oyster shell whiting need shine at grinder to 250 order, tail over 1-5%.
Further, follow according to mixing adulterant of the present invention, described waste incineration is given up also needs Wingdale and the coal ash mixture of interpolation 10% mass ratio in ash.
Embodiment
Below in conjunction with the ratio of mixture of compound, the invention will be further described.
Embodiment 1
The present embodiment is made up of the raw material of once weight proportion:
Hydroxyapatite 15%, oyster shell whiting 5%, the useless ash 10% of waste incineration, silicate cement 70%.
Various raw material was milled to 200 mesh sieves on shredder, tailed over 1-5%, mixed.
Embodiment 2
Hydroxyapatite 10%, oyster shell whiting 10%, the useless ash 5% of waste incineration, silicate cement 75%.
Various raw material was milled to 200 mesh sieves on shredder, tailed over 1-5%, mixed.
Implement conclusion
When the ratio of hydroxyapatite is 15%, the anti-sulphates corrosive effect that cement is best can be obtained.When the oyster shell whiting ratio of mixing is 10%, cement obtains best anti-freezing property, and meanwhile, weight loss and the loss of strength of cement are minimum.When waste incineration give up the ratio of ash reach 10% time, the crushing resistance of cement and anti-carbonization and leakproof are all better than the useless ash of the waste incineration only having 5% ratio.So for the different qualities of three kinds of adulterants, user can blend proportion voluntarily, to obtain the cement satisfied the demands.
