High-strength lightweight concrete: We build our future - High-strength lightweight concrete - new kind of structural lightweight concrete

Registration

2 TIMES LIGHTER

the concrete has average density 1300-1500 kg/m³ that representing almost half of the traditional heavy concrete.

R_com MORE THAN B45

compressive strength of the concrete can reach 60-70 MPa and specific strength not less than 35-40 MPa.

POROSITY FROM 33%

the concrete structure is saturated with gas phase (total porosity - 33-38% where closed pores are 32-36% and opened pores are 1-2%.

2-4 TIMES WARMER

the concrete has higher thermophysical properties and 2-4 times best the insulating capacity.

F300 FROST CYCLES

the concrete has low open porosity and water absorption that create the conditions for increasing of frost resistance up to F300.

25% MORE EFFICIENT

unique operational properties provide high economic efficiency (more than 30%) during construction and operation.

High-strength lightweight concrete

Details: Created: 01 June 2012

Scientific and technical goal of project "High-strength lightweight concrete" is creation of technology of high-quality building materials to increase efficiency of building and decreasing the cost of the specific area. Main task to achieve this goal is formulated: develope technology of new kind of concrete multifunctionaldestinationwitha universal set ofperformance properties.

Improving the quality of concrete as a most popular building material is a global trend which aimed to combine the positive attributes of light and heavy concretes. That is decreasing the average density and increasing the strength of concrete can to provide structural and heat insulating properties of these materials at the same time. But reduction the density of concrete less than 1800 kg/m³ leads to significant loss of strength and bearing capacity all in all.

Authors of this project developed technology of energy-efficient high-strength lightweight concrete (HSLWC) which has average density 1300-1500 kg/m³ and class of strength more than B45. Our concrete is almosttwice lighter and warmer than traditional heavy concrete, but it has the same high strength and freeze-thaw resistance (more than F300). Such properties are not possible for cellular concrete which are used today.

The high-strength lightweight concrete is fine-grained concrete which contains microscale spherical particles of filler. These microspheres together with special components of the cement-mineral composition and peculiar modifiers allow to form the dense and strong structure of the concrete with intense closed porosity at the same time.

The developed conrete is classified as material for construction with high operational properties. It can be used for building of multi-storey and high-rise buildings, railway and automobile bridges, overpasses, junction, manufacturing of big-span reinforced concrete products (girders, beams, crossbars, etc.) and other special difficult building objects.

Application of the high-strength lightweight concrete for construction allows:

reduce the weight of the building and increase the maximum number of floors (up to 40%) due to low average density of concretes;
reduce the requirements for the grounds and foundations and reduce the total cost of works at "zero cycle" 2-2.5 times;
reduce the consumption of materials due to economy of concrete and metal reinforcement;
improve the energy efficiency of the building during its operation (energy saving in heating);
reduce the cost of transport and installation works in building process due to using the less lifting equipments;
reduce the cost of one square meter of housing in high-rise building at 30%.

Total efficiency of construction is increased at 30-35% due to application of high-strength lightweight concrete!
