In this study the Sugar cane bagasse ash (SCBA) was characterized for chemical composition, morphological and mineralogical properties. From XRF analysis it found that SCBA has SiO2, Al2O3, Fe2O3 CaO content of 67.25%, 6.37%, 4.21% 13% respectively a very low LOI value 0.34% can be classified as Class F ASTM pozzolan according to C 618-2009. used pozzolanic material after grinding less than 45 ...

Abstract This study analyses, by means of lifespan cost and assessment, the production binary concrete admixtures compound artificial pozzolan demolition waste. Ten formulations were developed, differentiating them in terms mixtures, binder aggregate content, order to verify their potential use columns. The replacements 25% Portland cement for fly ash rice husk ash, 15% 30% natural coarse aggre...

This paper provides a continuation of ‘The Characteristics and Properties of Rubbing Bricks used for Gauged Brickwork – Part One’, published by Gerard Lynch and Sara Pavía in the March 2003 issue of the Journal of Architectural Conservation. In this, the authors examined the historical background, raw materials, production methods, use, and weathering characteristics of rubbing bricks. Despite ...

As a by-product generated from the processing of corn, the production in China of corncob (CC) is abundant, with up to 3.87 million tons per year. The biomass gasification industries make use of the CC residue as feedstock, but large volumes of generated corncob ash (CCA) requires daily disposal. In this study, CCA was characterized by laser particle size analyzer (LPSA), X-ray fluorescence (XR...

In this study, waste ash was utilized as a pozzolanic material in blended Portland cement in order to reduce negative environmental effects and landfill volume required to dispose of waste ash. The influence of waste ash, namely palm oil fuel ash, rice husk ash and fly ash on compressive strength and sulfate resistance in mortar were studied and evaluated by some accelerated short-term techniqu...

Class F fly ash cannot be used alone in soil stabilization applications as it is not selfcementing. An activator such as Portland cement or lime must be added to produce cementitious products often called pozzolan stabilized mixtures. The developed mixture must possess adequate strength and durability, should be easily compacted, and most importantly should be economical and environmentally fri...

More sustainable and environmentally friendly concretes are essential to reduce the climatic environmental impact of growing demand for concrete fuel urban sprawl. This manuscript reports on an experimental study designed test fire resistance one such concrete, prepared contain natural zeolite-bearing tuff. The containing zeolites has received little attention is therefore poorly understood. Re...
