Green building using nano materials for high performance cement mortar composite
The present paper presents the work of using nano cement mortar to be used in the green building construction was developed resulted to high performance in mechanical properties, such as compressive and flexural strengths, that will minimize the the need for massive quantities of the construction materials that eventually will reduce the carbon footprint due to the reduction in the energy consumption used for the construction material. Different cubes and prisms were cast and tested for determining the compressive and flexural strengths (modulus of rupture) of nano cement mortar. The parameters considered were micro sand, micro cement sulphate resistance conforming ASTM C150 type II, particle size (45–0.7)μm, micro sand (300–75)μm, conforming ASTM C33, nano silica (500–100)μm. Naphthalene sulphonate was used as super-plasticizers. The cement mortar matrices were considered in four groups.
Development of Nanocement Mortar as a Construction Material
The present research examined the compressive and flexural strength of nanocement mortar by using micro cement, micro sand, nanosilica and nanoclay in developing a nanocement mortar which can lead to improvements in ferrocement construction. The measured results demonstrate the increase in compressive and flexural strength of mortars at early stages of hardening. In addition, the influence of heating on compressive strength of cement mortar. General expressions to predict the compressive strength, modulus of rupture for the developed nanocement mortar in the present work are proposed.
