This paper presents the effect of reinforced high performance concrete (HPC) in exterior beam-column joint with and without fibre under monotonic loading. In this experimental investigation, cross-diagonal bars have been provided at the joint for reducing the congestion of reinforcement in joints, and also M75 grade of concrete with optimum mix proportion of 10 % silica fume and 0.3 % glass fibre was used. Four exterior beam-column joint sub-assemblages were tested. The specimens were divided into two types based on the reinforcement detailing. Type A comprises two joint sub-assemblages with joint detailing as per construction code of practice in India (IS 456-2000), and Type B comprises two joint subassemblages with joint detailing as per ductile detailing code of practice in India (IS 13920-1993). In each group there was one specimen of control mix and the remaining one specimen of fibre-reinforced mix. All the test specimens were designed to satisfy the strong column-weak beam concept. The performances of specimens were compared with the control mix and the fibre-reinforced mix. The results show that exterior beam-column joint specimens with silica fume and glass fibre in the HPC mix showed better performance.

Denim fabrics are in general manufactured by using 100% cotton fibers. A novel attempt has been made by using bamboo/cotton yarns in warp and weft directions to produce denim fabrics using ring yarns in warp and rotor yarns in weft directions. In this research work, bamboo/cotton yarns are manufactured in different blend compositions like 100% bamboo, 100% cotton,70:30, 50:50 and 30:70 ratios. Ne 10 and Ne 16 carded yarns are manufactured from both the ring and rotor spinning systems. The yarns manufactured out of these two spinning systems have been critically analyzed for their quality characteristics like Unevenness, Imperfections, Hairiness, friction, abrasion, strength and elongation. The influence of blend ratios on yarn quality characteristics in ring and rotor yarns has been analyzed and the optimum blend proportion which gives the best quality has been investigated.

This research paper pacts with the analytical examination of synthetic fibres (Polypropylene and Recycled polyethylene terephthalate RPET) and steel fibres in reinforced exterior beam column joint by using ANSYS. Based on IS 10262-2009, M40 grade of concrete was prepared along by volume fractions up to 0.5% of synthetic and steel fibre. 9 number of exterior beam column joint with various proportions of hybrid fibre incorporated reinforced concrete specimens were tested by means of monotonic loading. Their experimental results exhibited that reinforced concrete exterior beam column joint specimens with hybrid fibre specimens achieved superior performance along with high ductility, high strength and less crack patterns. The main aim of this research paper was based on the experimental input, analytical examination by ANSYS was carried out and related with the experimental results found. The comparison showed that both the experimental and numerical results similar.

Nowadays, waste materials are becoming issue to the environmental pollution, which is a danger to the climate and the general public. It is imperative to reuse these materials and clear them in an appropriate manner. Waste can be utilized in the infrastructure development by two different ways: reusing and by recycling. The old-style methods for creating materials for construction are from available natural resources. If we continue the same there will be no more resources left, to avoid such cases we are practicing to recycle and reuse the solid waste in an effective manner. Owing to the development of industrial and urban management systems, a greater number of solid wastes are generated which is currently disposing them into the land and this causes various problems to the society and environment. To protect the environment from the threats, lot of efforts are being developed for recycling of variety of solid wastes in order to employ them in the creation of various building materials. In this paper, we have discussed about the recycling potentials of solid waste and possible utilization of waste materials in the construction industry.
