White Cement Concrete as an Element Sustainable Construction

Abstract

The effect of materials on local air temperature is a rapid expansion of research. Basic research in this area is directed to color and the composition of materials and their ability to reflect or absorb (and emit) solar radiation. The color and composition of materials greatly affect the temperature Materials exposed to solar radiation. The thermal energy from the absorbed solar radiation will They eventually enter the surrounding atmosphere, causing local heating. Smog levels It has also been associated with high temperature. Thus, as urban temperature It increases, as does the potential for smog and pollution. One of the discounted items, among other things, the above-mentioned negative effects on the environment are white Cement. White cement concrete is very popular with architects thanks to it Pure and uniform appearance. The paper presents the properties of white cement, white Concrete and the benefits of its use as a component of sustainable construction practice.

The main research significance is producing white concrete mix by using sustainable white material made from natural material and compare it with normal concrete the results that this study conclude was:

White concrete made from white material with cubic compressive strength (35.), cylindrical compressive strength (277 MPa) at 28 days of curing and density (2274   kg/m3) it can be used in the structure's construction. Otherwise, the cubic compressive strength of the normal concrete was (29.2 MPa) cylindrical compressive strength (25 MPa) at 28 days of curing and density ( 2474 kg/m3).

Splitting Tensile Strength was 3.57 for Wc and 3.64 for Nc at age of curing 28 days, percentage decrease in the tensile strength for white concrete by 3% to the normal concrete as a reference mix due to the density of the mix.

Flexural Tensile Strength (Modulus of Rupture )74 for white concrete and 5.1 for normal concrete. there were an decrease by 7% compared to reference mix.
