Effect of layered double hydroxide (Mg-Al) reinforced in concrete for enhancing thermal comfort

Abstract

Experimental study was done on the effect of layered double hydroxide (LDH) Magnesium-Aluminium (Mg-Al) on M20 grade concrete. Different weight percentage (0.5, 0.75, 1.0 & 1.25 Weight percentage of cement) of MgAl LDH as nano material was added with cement concrete cubes. These cubes were tested for X-ray diffraction (XRD), temperature absorption measurement and compressive strength. The XRD pattern of the concrete cubes shows the presence of MgAl LDH without any reaction with concrete. To find the compressive strength of the M20 concrete cubes contains with MgAl LDH, compressive strength test was performed. The experimental investigation shows the optimum percentage of MgAl LDH to be added for giving maximum temperature absorption without affecting the compressive strength and it is proved from the result that there is absorption of temperature to improve the thermal comfort.
