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.
Nano cement mortars for construction materials
Abstract Nano cement mortar refers to the uses of nanomaterials to enhance the structure and property of mortar. Various nanomaterials can be used effectively in mortar, such as nano-SiO2, nano-Fe2O3, nano-Al2O3, nano-TiO2, nanoclay, nano-polymer mesh … This chapter focuses on the fabrication and mechanical property of nano cement mortars containing nanosilica fume, nano-metakaolin, nano polymercement.
Factors Likely to Influence Tort Litigation in the European Union
As the European Union moves towards harmonization in a variety of business, political, and regulatory settings, an opportunity exists to influence the form of tort liability found in these nations. The opportunity should not be missed, with rising concern that U.S. influences will set into motion costly litigiousness, particularly as EU member nations pull back on the level of social programmes available to cover costs typically included in tort claims. To assist policymakers in their deliberations about European Union tort directives, this paper provides discussion of the frequently cited key differences between the U.S. tort systems and what is found in most EU member nations. The discussion is focused on available evidence regarding the influences of these differences as well as important areas of future research. The most important areas seem to be (1) the need to enforce European Law when no defined regulatory body exists for this purpose; (2) the connection between government social programmes and the need for tort liability compensation; (3) and the influence of rules governing payment of legal costs and lawyer fees.
