Optimizing the Use of Fly Ash in Concrete Cold weather and winter conditions can be challenging when concrete contains fly ash. Especially when used at higher levels, fly ash concrete typically has extended setting times and slow strength gain, leading to low earlyage strengths and delays in rate of construction. In addition, concretes containing fly ash are often reported to be more ...

This is an experimental study which explores the physical, mechanical, and economic factors involved in the production of type CEM II AB/W cement. In this context, 4 cement additives were used in two different dosages (200 and 800 g/t). Class C fly ash was used for composite cement production at ratios of 5%, 20%, and 35%.
The fly ash in the concrete is replaced at a percentage o f 30%, 40% and 50%. The polypropylene Fibre is added to concrete by its volume fraction of %, %, 0. 25% and %. The results obtained by this experime nt is that the fly ash possesses good strength in concrete and as the percentage of polypropylene fibre % to % will leads to good strength.

In this study, the degradation behavior of circulating fluidized bed (CFB) fly ash reinforced unsaturated polyester composites at different loadings of 0%, 10%, 20%, 30%, and 40% CFB fly ash were observed at different temperatures of 30°C, 50°C, and 80°C under acidic environment. The mass uptakes of the samples were recorded at specified time intervals to determine the effects of fly ash ...
Murahari and Rao [10]; studied the effect of polypropylene fibres in fly ash concrete. Fibre volume fraction of %, %, % and % was used in fly ash concrete with class C fly ash of specific gravity, obtained from NLC. Fly ash content was varied as 30%, 40% and 50%. 12 mm (40%) and 20mm (60%) coarse aggregate with specific ...
Poly(propylene) homopolymer/fly ash (50% wt) composites have been prepared from two samples of fly ash that differ in terms of the geographic source of coal feedstock, which left one of the samples with a higher group I and II metal content. A screening study indied that Lubrizol Solplus® C800 (an unsaturated carboxylic acid dimer coupling agent), initiated with dicumyl peroxide, conferred ...

Fly ash (left) and propylene fibres Forta Ferro (right). With respect to limited scope of the article, the paper is focused only on two laboratory tests: unconfined compression strength test and direct shear test. On these types of test, the influence of fibres can be easily demonstrated. Three types of tested mixture with different fibre content (0%, 1%, 2%, related to the dry unit weight ...
exemplary case of the ethylenepropylene random copolymer RCP1: While the modulus is increased – in combination with embrittlement – by the steam sterilization due to recrystallization, the elongation at break drops massively for both irradiation techniques. The effect is even stronger for the γradiation sterilization, which actually confirms that β or electron beam irradiation is ...
