An Experimental Study on Concrete by Replacement of Coarse Aggregate with Demolished Building Waste in Crushed Concrete
Abstract: A large amount of construction and demolition wastes are produced annually in India. These waste materials require a large place to dispose and then the disposal of wastes has become a severe problem. The continuous use of natural resources for making conventional concrete leads to the reduction in their availability and results in the increase of the cost of the coarse aggregate and fine aggregate. The possible use of recycling …

Optimizing Aggregate Gradation for Enhancing Strength Properties of Pervious Concrete
Abstract: Pervious concrete possesses high permeability enabling environmental applications like stormwater recharging. However, lower strength limits widespread infrastructure adoption necessitating enhancements. This study focuses on optimizing aggregate proportions for improving compressive and flexural strength. Mixes were developed with cement variations from 200-500 kg/m3 with fine to coarse aggregates ratios systematically altered. Strengths were measured as per ASTM C39 and ASTM C78. Results showed reduced water-cement ratio and balanced aggregate blends improved …

Spatial and Temporal Variation of Bioaerosols with Meteorology at Different Land Sites
Abstract: Air particulates associated with biological origins are termed as bioaerosols. These bioaerosols consist of different species of bacteria, fungi, pollen and spores, etc. and can be allergenic and infectious in nature. The study is an attempt to understand the seasonal variation in bioaerosols concentration at three different land use sites: site I (commercial site), site II (dumping site), Site III (vegetated site). Statistical correlation was applied to infer the relation …
