Abstract
The invention provides a method for preparing concrete admixture by compounding ultrafine fly ash, which is to grind the fly ash to a specific surface area of more than 1.0m by using an ultrafine mill2The concrete pumping agent is prepared with naphthalene water reducing agent, calcium carbonate and superfine ash in the ratio of 1 to 0.2-0.5 to 8-25, and through compounding special additive for high strength concrete with naphthalene water reducing agent and superfine flyash in the ratio of 1 to 8-25, and compounding waterproof agent with alumina, MC, water reducing agent and superfine flyash in the ratio of 1 to 3-5 to 20-50.
Description
The present invention relates to a kind of series concrete admixture, particularly utilize industrial residue flyash, through high-tech development, the concrete batching compound additive is widely used in the various concrete workses of industries such as building, traffic, water conservancy, mine, metallurgy.
The disposal of industrial residue flyash and utilization are to have global key subjects, development and use at developed country's flyash have caused enough attention, have road-making material, concrete and mortar Additive, produce cement, plastic filler, extraction useful element, firing ceramics, production composite fertilizer etc.But flyash is carried out super-fine processing to be used seldom.
The objective of the invention is to flyash is carried out super-fine processing, surface active excites the activity of flyash, and with flyash as active carrier, the preparation compound additive.Can be widely used in various concrete workses.
The objective of the invention is to be achieved through the following technical solutions:
Utilize super fine-ground fly-ash to be major ingredient, compound several chemical feedstockss are mixed with powdered coal ash composite additive, it is characterized in that with ultra-fine mills such as vibration mill or airflow milling flyash being milled to specific surface area greater than 1.0m
2/ g, compound with water reducer, auxiliary other component is made the multiple concrete admixture of fine; Pumping agent is made up of naphthalene series high-efficiency water-reducing agent, wooden calcium water reducer, superfined flyash, and its configuration proportion is followed successively by 1: 0.2-0.5: 8-25 is mixed evenly with concrete mixer; Preparation high-strength concrete special-purpose admixture, use naphthalene series high-efficiency water-reducing agent, superfined flyash in 1: the ratio of 8-25 is mixed evenly with mixer; Press 1 with aluminum oxide, MC, water reducer, superfined flyash: 3-5: 3-5: 20-50, accurately the metering back is mixed evenly with mixer.
Illustrate below:
Example 1:, join silks and become the flyash pumping agent with naphthalene series high-efficiency water-reducing agent, wooden calcium, superfined flyash 1: 0.5: 12 in proportion.Mix in the concrete by cement consumption 10% and (to replace 10% cement simultaneously), its pump concrete performance is as follows:
| The slump (mm) № initial 0.5 hour 1 hour | Ultimate compression strength (Mpa) 3 days 7 days 28 days 90 days |
| ????1????200????185????170 ????2????220????190????175 | ????28.2??45.3??58.7??70.6 ????45.8??63.5??79.6??88.1 |
Annotate: № .1 cement consumption 450kg, sand coarse aggregate ratio 0.40, water cement ratio is 0.35,425#
Slag cement
№ .2 cement consumption 500kg, sand coarse aggregate ratio 0.40, water cement ratio is 0.30,525#
Ordinary portland cement
High-strength concrete special-purpose admixture of the present invention, with naphthalene series high-efficiency water-reducing agent and superfined flyash in 1: the ratio of 8-25 evenly is mixed with mixer.Can prepare the high-strength concrete and the High Strength Pump Concrete of multiple strength grade according to the volume of the fineness of flyash and water reducer.
Example 2: with flyash super-fine processing to specific surface area is 1.15m
2/ g, naphthalene series high-efficiency water-reducing agent is mixed evenly in 1: 10 ratio.Admixture is joined in the concrete by 12% of cement consumption.
Claims (4)
1, utilizes the manufacture method of superfined flyash composite concrete additives, utilize super fine-ground fly-ash to be major ingredient, compound several chemical feedstocks is mixed with powdered coal ash composite additive, it is characterized in that with ultra-fine mills such as vibration mill or airflow milling flyash being milled to specific surface area greater than 1.0m
