Purpose of the development: Production of low-power composite cement and concrete and solutions based on it.

Recommended application field: Building materials industry.

Technical characteristic: Introduction 50% of Portland cement compositions flyash and blast furnace slag in a ratio of 3: 1 (by weight) of the specific surface of 450 ... 550 m2 / kg and applying additives PFM comprising grinding aids and JV likarboksilatnogo type enables Activity more than 60 MPa. Based modified with the additional administration of KC porogen Ufapore 0,04 ... 0,11% (wt.%) May be obtained for light dry mix mortars average density of 1100 ... 1500 kg / m3 and a strength of 12 ... 25 MPa. The use of ash-containing additives with KC PFM containing SP polycarboxylate type allows you to get cast and samouschilnyuvalni concrete with compressive strength at the age of 65 to 28 days ... 92 MPa. These concretes are characterized by intense strength development in the early stages of hardening - strength in one-day age reaches at least 35%, and in three daily - 50% of the design strength. At low values of B / C (B / D <0.3) increase the amount of fly ash with 30% to 40% by weight of the cement does not lead to a substantial drop in compressive strength of the concrete.

The development stage readiness: Introduced in production

Technical and economic effect: Technical and economic effect achieved when using ash-containing additives KC with PFM, due to a decrease in the cost of Portland cement clinker by 30 ... 50%, as well as a decrease in energy costs while significantly improving performance.

Description of the development:
()
Experimental tests have shown the possibility of ash-containing composite cement (KC) activity greater than 60 MPa using a polyfunctional modifier additives (PFM), comprising superplasticizers, including new generation, as well as grinding aids for reducing power consumption in the specific surface of 450-550 m2 / kg . On the basis of the modified composite cements investigated complex technological aspects related to obtaining high-tech concretes new generation of High Performance Concrete (HPC), as well as porous effective solutions.
