Cement is the most sought material in world next to water. The manufacturing and utilization of cement increasing rapidly leading global warming due release CO2. In this research, it intended partially substitute with agro-based byproducts i.e. bagasse ash (SCBA) as supplementary cementitious materials (SCM). Meanwhile, effect SCBA (added at various proportions 5–30 %) on compressive tensile st...

Using biomass waste as supplementary cementing material (SCM) in concrete has attracted researchers’ attention for efficient utilization and reducing cement demand. Sugarcane bagasse ash (SCBA) is one such example of waste. It an agricultural obtained when sugarcane from the sugar industry used power generation disposed open-air dumping sites. Its disposal causes particulate matter, degrading a...

The purpose of this study was to investigate left-ventricular function during strenuous exercise with the self-contained breathing apparatus (SCBA). With the use of two-dimensional echocardiography, images of the left ventricle (LV) were acquired during sustained exercise (3 x 10 min) under two conditions: 1) SCBA, or 2) low resistance breathing valve. Twenty healthy men volunteered for the stu...
