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.
State estimation for integrated vehicle dynamics control
This paper discusses a vehicle controller and a state estimator that was implemented and tested in a vehicle equipped with a combined braking and chassis control system to improve handling. The vehicle dynamics controller consists of a feed forward body roll compensation and a feedback stability controller. The estimator is based on a non-linear vehicle model combined with an extended Kalman filter. The Kalman filter is also connected to an algorithm, which estimates the tyre-road friction coefficient. The developed estimator was tested in a vehicle. Good results were achieved for normal and extreme driving manoeuvers.
