Abstract
The invention belongs to a cement reinforced grade-increasing agent and particularly relates to a fly ash composite cement reinforced grade-increasing agent and a preparation method thereof. The grade-increasing agent is prepared from the following raw materials: fly ash, triethanolamine, sodium chloride, sodium sulfate and a water reducer. The grade-increasing agent is mixed into 325-grade cement of which the property completely exceeds the property of 425-grade cement, the required raw materials are mostly easily available and inexpensive, the product can be produced in batches at normal temperature and pressure, the grade-increasing agent is safe and reliable, the economic benefits and market competitive advantage are significant after the grade-increasing agent is put into the market and the grade-increasing agent is conductive to popularization.
Description
technical field:
The invention belongs to cement and strengthen standard-increasing agent, be specially a kind of flyash compound cement and strengthen standard-increasing agent and preparation method thereof.
background technology:
Volcanic ash is a kind of good natural building cementing material, flyash has potential pozzolanic, but also need rationally to excite and just can show this activity afterwards, and now conventional flyash activity mode of excitation, all fully can not excite this activity fast and effectively, the utilization of flyash is very limited, if flyash can be at normal temperatures and pressures, activity excitation is effectively solved, so flyash will as volcanic ash, become a kind of resource cheap and easy to get, this is also that flyash studies real value place.
summary of the invention:
Therefore, be necessary that inventing a kind of flyash compound cement strengthens standard-increasing agent and preparation method thereof.
A kind of flyash compound cement strengthens standard-increasing agent and preparation method thereof, desired raw material comprises flyash, trolamine, sodium-chlor, sodium sulfate and water reducer, its proportion relation is 10000 parts, flyash, trolamine 4 ~ 5 parts, 150 ~ 200 parts, sodium-chlor, 150 ~ 200 parts, sodium sulfate, water reducer 50 ~ 100 parts, the former base cement that aforementioned proportion can strengthen is 10000 parts.
By flyash, trolamine, sodium-chlor, sodium sulfate and water reducer, be a kind of flyash compound cement according to the ratio uniform mixing of 10000:4 ~ 5:150 ~ 200:150 ~ 200:50 ~ 100 and strengthen standard-increasing agent product.
Preferably, the sodium-chlor in raw material and sodium sulfate stem from calcium carbide waste slag.
With 325 grade cement citings, be mixed in 325 grade cement according to aforementioned proportion by the present invention, its performance surmounts the performance of 425 grade cement completely, in like manner, be mixed into 425 cement, also can strengthen and surmount 525 cement performances, its desired raw material is mostly cheap and easy to get, wherein flyash and calcium carbide waste slag also belong to industrial waste, while turning waste into wealth, namely product can be mass at normal temperatures and pressures, safe and reliable, its put goods on the market after economic benefit and market competition advantage obvious, be beneficial to popularization.
embodiment:
A kind of flyash compound cement strengthens standard-increasing agent and preparation method thereof, desired raw material comprises flyash, trolamine, sodium-chlor, sodium sulfate and water reducer, its proportion relation is 10000 parts, flyash, trolamine 4 ~ 5 parts, 150 ~ 200 parts, sodium-chlor, 150 ~ 200 parts, sodium sulfate, water reducer 50 ~ 100 parts, the former base cement that aforementioned proportion can strengthen is 10000 parts.
By flyash, trolamine, sodium-chlor, sodium sulfate and water reducer, be a kind of flyash compound cement according to the ratio uniform mixing of 10000:4 ~ 5:150 ~ 200:150 ~ 200:50 ~ 100 and strengthen standard-increasing agent product.
Preferably, the sodium-chlor in raw material and sodium sulfate stem from calcium carbide waste slag.
Be below the crush test result of the present invention under synthermal physical environment:
Thin matter flyash granularity is less than 1mm, and thick matter flyash granularity is 1 ~ 1.5mm, and the present invention selects thick matter flyash optimum, but does not add the former base cement of high grade of the present invention with the effect of thin matter flyash is still far super.
