Abstract

In the current arena, infrastructure development holds the key for the development of every nation. Concrete is one of the most utilized materials by the construction industry which is a homogeneous material prepared of heterogeneous materials like Cement, sand and aggregate. However rapid urbanization has created a huge demand for natural sand hence made it even more expensive. Due to the high volume consumption all the natural resources are facing depletion. Industrial waste products are accumulating to an alarming level which makes the safe disposal of the industrial wastes a herculean task. An attempt has been made to study the behaviour of high performance concrete made with partial replacement of fine aggregates with used foundry sand. It is found that up to 30% of fine aggregate can be replaced with used foundry sand for the manufacture of high performance concrete reducing the usage of fresh fine aggregates and to minimize the exploitation of natural resources to a minimum balanced state with reduced ecological impact.

Keywords

High Performance Concrete, Used Foundry Sand, Workability, Compressive Strength.

Abstract

Optimisation is the controlling factor in every sort of manufacturing process for better productivity with minimal usage of labour, materials and power .In this context structural optimisation is a challenging task for the engineering fields connected with manufacturing. With the introduction of computers in the process of structural analysis, structural optimisation also underwent drastic developments. It is alarming that the natural resources are exhausting at a high rate due to the industrialisation and the higher per capita usage of different metallic and non metallic substances. So the materials should be utilized with minimum usage and maximum efficiency for the conservation of nature and to cater for the future needs. The advancement in structural optimisation is the only remedy resorted for the efficient utilization of the resources in a scientific way. Compared to other engineering fields the developments in structural optimisation in civil engineering field is still far behind. So a collaborative effort from the various experts in different specialisation in civil engineering is resorted to the effective utilisation of this method to the advancement of cost effective utilisation of various resources.

Keywords

Structural Optimisation, Objective Function, Design Variable, Geometric Parameterisation, Optimisation Algorithm.
