Concrete construction offers a great opportunity to replace the cement with a coal-based power plant waste—known as coal bottom ash (CBA)—which offers great environmental and technical benefits. These are significant in sustainable concrete construction. This study aims to recycle CBA in concrete and evaluate its particle fineness influence on workability, compressive and tensile strength ...

An experimental study was accomplished to study the effect of replacement of both cement and sand with coal bottom ash (CBA) on the properties of the concrete. Control mix was prepared without coal bottom ash replacement and nominated as series A. The mixes of series B were prepared with20 % replacement of cement with 30 hours ground coal bottom ash (GCBA).

Palm Oil Fuel Ash was sourced from Malaysia. The cement used was Portland cement– CEM I 52.5R (Snow Crete). Cement was replaced with POFA in concrete by volume at steps of 0%, 2.5%, 5%, 10%, 15% and 20%. The 0% replacement, also referred to as the control was taken as the point of reference from which all performance was measured.

This paper assesses the use of coal bottom ash as coarse aggregate replacement in a grade 15 concrete, in an attempt to contribute to a sound management of coal ash on the island of Mauritius. It specifically investigates the effect of the bottom ash on the compressive strength, workability, water absorption and resistance to sulphate attack of the concrete.

Pervious Concrete (PC) has long been used in surface runoff management. But one of its major drawbacks is its low strength. Several industrial wastes apparently contain properties that could aid the increase in strength of PC such as coal fly ash and fine sawdust. Thus, their utilization is a possib …

This paper presents the results of an experimental investigation on the effect of sieved coal bottom ash as a substitute for natural sand on the properties of concrete, when an extra 5%, 10%, 15%, 20%, 25% and 30% weight of cement was added. First, M-35 grade concrete was casted and tested; using a fixed percentage of 70% sieved coal bottom ash and 30% natural sand.

SHARDA UNIVERSITY. FLYASH REPLACEMENT OF CEMENT IN CONCRETE Ash Production and its availability Fly ash is one of the residues created during the combustion of coal in coal-fired power plants. Fine particles rise with flue gasses and are collected with electrostatic precipitators About 60% power is produced using coal as fuel in India. Indian coal is having low calorific value (30003500 Kcal ...

fly ash on compressive strength of concrete by partial replacement of cement with 0%, 10%, 20% and 30% of fly ash. The concrete mix of M20 grade was prepared as per IS10262:2009 having mix design ratio as 1:1.4:2.96 and w/c ratio of 0.50. To carry out the experimental investigation total 24 cubes of size 150mm x 150mm were casted. 6 cubes

The possibility of utilizing treated coal bottom ash as a partial replacement of Portland cement was examined through compressive strength test on mortar samples. A total of 16 batches of mortar mixtures with cement:sand ratio of 1:2.5 and 1:2.75 were prepared using two types of treated coal bottom ash. The chemical compositions including the unburned carbon of coal bottom ash were also analyzed.

In brief and in order to produce concrete-based materials that are sustainable, the use of cement replacement materials and recycled products is necessary. Cement replacement materials are necessary, including coal fly ash, ground granulated blastfurnace slag, silica fume, ground glass natural pozzolans or calcined clay (eg, metakaolin).
