Abstract
A foam concrete has constituents that include a cement, a sand, a coarse aggregate having a density in a range of 1400-1600 kg/m3, a water, and a foam solution. The foam solution includes a foaming agent and a foaming water. The foam concrete has a compressive strength of at least 20 MPa, a thermal conductivity of less than 0.40 W/mK and a maximum dry weight of 2000 kg/m3.
Claims20
A foam concrete, the constituents of the foam concrete comprising:
- a cement;
- a sand;
- a coarse aggregate having a density in a range of 1400-1600 kg/m3;
- a water;
- and
- a foam solution;
- wherein
- the foam solution includes a foaming agent and a foaming water;
- and
- the foam concrete has a compressive strength of at least 20 MPa, a thermal conductivity of less than 0.40 W/mK and a maximum dry weight of 2000 kg/m3.
A foam concrete, the constituents of the foam concrete comprising:
- a cement in an amount of 55.6 to 57.8 wt % of the constituents of the foam concrete;
- a sand in an amount of 11.1 to 11.5 wt % of the constituents of the foam concrete;
- a coarse aggregate in an amount of 11.1 to 11.5 wt % of the constituents of the foam concrete, the coarse aggregate having a density in a range of 1400-1600 kg/m3;
- a water in an amount of 17.9 to 21.1 wt % of the constituents of the foam concrete;
- and
- a foam solution in an amount of 1.1 to 2.8 wt % of the constituents of the foam concrete, each based on the weight of the foam concrete.
A method of forming a foam concrete, the method comprising the steps of:
- mixing together the following constituents:
- a cement;
- a sand;
- a coarse aggregate having a density in a range of 1400-1600 kg/m3;
- and
- a water;
- and
- adding a foam solution that includes a foaming agent and a foaming water to arrive at the foam concrete that has a compressive strength of at least 20 MPa, a thermal conductivity of less than 0.40 W/mK and a maximum dry weight of 2000 kg/m3.
