Abstract

A kind of method of manufacture and use thereof that relates to silicate series cement compounded reinforcer, its principal character is three kinds of set of dispense ratios of composite fortifier, the powdery composite fortifier 2-4% of getting its arbitrary set of dispense ratio is made cement with 98-96% cement raw material grinding; Perhaps contain trolamine or calcium lignin sulphonate proportioning component, its two kinds of raw materials are made solution, be sprayed on the cement raw material, grinding is made cement then, and its product meets GB GB1344-85 standard, major advantage: cement early strength height, stable long-term strength has grinding aid, solves the bad effect of stability, has remarkable economical and social benefit.

Description

Silicate series cement compounded reinforcer

The present invention relates to a kind of composite fortifier of gaining in strength that silicate series cement is had.

Present cement intensifier both domestic and external is that one or both mixtures of raw material are as toughener with trolamine, sodium sulfate, sodium-chlor mostly, or add other material, the shortcoming of its existence: use sodium sulfate and materials such as sodium-chlor and trolamine, cook concrete admixture, the cement type that is suitable for has limitation, and modified effect is not satisfactory, and directly mixes in the concrete, with cement, gather materials that it is uneven to mix, easily cause whole pre-member, structural part strength variance big.

The purpose of this invention is to provide a kind of silicate series cement compounded reinforcer, this product not only can improve strength of cement effectively, and can reach and reduce cost, and improves the purpose of output.

The present invention compared with prior art has the following advantages:

1, the present invention have promote cement crystal development, cement early strength height, later strength increase stable, workability is good, advantage such as bleeding not;

2, the present invention be with this composite fortifier with the cement raw material grinding, mix, resistance to frost is good, and has grinding aid and solve f-c and cause the effect that stability is bad;

3, adopt this toughener to produce with label cement, can mix blended material 10-15% more, or keep each proportioning raw materials constant, strength of cement can improve a label;

4, owing to add this composite fortifier in the cement, solved on the one hand and produced, can reduce 3-5Kg coal/ton cement, on the other hand coal gangue (or boiling furnace slag) has been turned waste into wealth with the big shortcoming of label cement power consumption, both solve environmental pollution problems, improved cement quality again.

Because 1m is whenever watered in the improvement of cement quality ³Concrete can be saved cement 10-15%, all adopts this technology as each cement mill, the whole nation, can save nearly ten million ton of cement every year, is equivalent to build more and produces 20 in 500,000 tons of cement mill per year, has remarkable social benefit and economic benefit.

Details are as follows for particular content of the present invention:

1, the component proportioning of cement compounded reinforcer of the present invention has three groups:

(1), calcium lignin sulphonate 2.5-5%, ferrous sulfate 30-20%, coal gangue (or boiling furnace slag) 67.5-75%, all % meter by weight;

(2), calcium lignin sulphonate 2.5-5%, sodium sulfate 30-20%, Sodium Nitrite 5-6%, sodium-chlor 5-6.5%, coal gangue (or boiling furnace slag) 57.5-62.5%, % meter by weight;

(3), sodium-chlor 49.995-49.990%, trolamine 0.01-0.02%, Sodium Nitrite 49.995-49.990%, all % meter by weight.

2, the manufacturing of silicate series cement compounded reinforcer and use processing method:

(1), get any of above-mentioned three groups of composite fortifier component proportionings, after mixing according to the above ratio, place crusher broken, make the powdery composite fortifier of granularity＜5mm;

(2), with the powdery composite fortifier of 2-4% and the cement raw material of 98-96%, be transported to grinding in the grinding machine together, make cement, its product meets GB GB1344-85 standard, the use of can dispatching from the factory;

(3), contain the proportioning component of trolamine or calcium lignin sulphonate, its two kinds of raw materials are pressed after proportioning in the component takes out, make 30% solution, be sprayed on the cement raw material with spraying gun, (other proportioning raw materials is constant), grinding gets final product then.

Embodiment:

Get 1 ton of cement, add the 2kg calcium lignin sulphonate, the 10kg ferrous sulfate, the 28kg coal gangue all places crusher to be broken into the powdery composite fortifier of granularity＜5mm, goes into mill with cement raw material again, makes cement, the use of can dispatching from the factory.

Claims (1)

1, the present invention relates to a kind of silicate series cement compounded reinforcer, it is characterized in that:

The component proportioning of cement compounded reinforcer:

(1), calcium lignin sulphonate 2.5-5%, ferrous sulfate 30-20%, coal gangue (or boiling furnace slag) 67.5-75%, all % meter by weight;

(2), calcium lignin sulphonate 2.5-5%, sodium sulfate 30-20%, Sodium Nitrite 5-6%, sodium-chlor 5-6.5%, coal gangue (or boiling furnace slag) 57.5-62.5%, % meter by weight;

(3), sodium-chlor 49.995-49.990%, trolamine 0.01-0.02%, Sodium Nitrite 49.995-49.990%, all % meter by weight.

The manufacturing of silicate series cement compounded reinforcer and use processing method:

(1), get any of above-mentioned three groups of composite fortifier component proportionings, after mixing according to the above ratio, place crusher broken, make the powdery composite fortifier of granularity＜5mm;

(2), with the powdery composite fortifier of 2-4% and the cement raw material of 98-96%, be transported to grinding in the grinding machine together, make cement, its product meets GB GB1344-85 standard, the use of can dispatching from the factory;

(3), contain the proportioning component of trolamine or calcium lignin sulphonate, its two kinds of raw materials are pressed after proportioning in the component takes out, make 30% solution, be sprayed on the cement raw material with spraying gun, (other proportioning raw materials is constant), grinding gets final product then.
