Fly ash additive caused a clear decrease of compressive strength in concretes analyzed at an early age, that is, after 3 and 7 days. According to Table 10, value f cm after 72 h of curing was almost 8 and exactly 10 MPa higher in concrete without the fly ash additive in comparison to FA-20 and FA-30, respectively. After a week, the differences

Abstract. This study focuses on the mechanical, fracture and durability characteristics of self-compacting high-strength concrete (SCHSC) containing recycled polypropylene plastic particles (RPPP) with and without silica fume (SF).

The addition of 4% hook ended steel fibers with fly ash, the compressive strength of concrete after 28-d curing was higher and increased sharply with the increment of fly ash content up to 10 %. The addition of fly ash with 4% steel fibers minimized the sorptivity of SIFCON in 28- days of curing.

PROPERTIES OF SELF-COMPACTING CONCRETE CONTAINING TYPE C FLY ASH Marina Jovanović, Adnan Mujkanović, Asim Čamdžić, Denis Vejzović Faculty of Metallurgy and Materials, Zenica, FBiH ABSTRACT This paper presents results of investigation of possibility of use Class C fly ash in self compacting concrete (SCC) production.

Hence, in a non-conventional concrete with a very different mixture such as self-compacting concrete (SCC) incorporating a high volume of fly ash, the sorptivity is expected to be different from that of the concrete. This paper aims to determine the influence of high volume fly ash contents on the sorptivity of SCCs, as measured by the method

Mechanical and Durability Performance of Self Compacting Concrete Containing Fly Ash and Metakaolin Dr. Rizwan A. Khan * Associate Professor, Department of Civil Engineering, Aligarh Muslim University Aligarh, UP ,India, 202002 Abstract This paper is concerned with Self compacting concrete (SCC) which is a highly flow-able, non-segregating

Also, the use of fly ash improves rheological properties and reduces cracking of concrete due to the heat of hydration of the cement (6). Kim et al. (7) studied the properties of super flowing concrete containing fly ash and reported that the replacem ent of cement by 30% ( 40% for only one mixture)

The main aim of this literature review is to identify how green concrete can help towards promotion of sustainable built environment. The present study outlines literature related to green concrete manufactured from some industrial wastes such as fly ash, silica fume, slag modified, glass modified, rubber modified and recycled aggregate concrete.

Dhiyaneshwaran.S ( )[10] had investigated about the workability and durability characteristics of self compacting concrete containing Viscosity modifying admixture and class F fly-ash. The workability of the concrete is determined by conducting slump flow, V- funnel, L-box and U-box tests and the durability of the concrete is computed using

Abstract This paper presents mechanical and durability properties of geopolymer concrete containing recycled coarse aggregate (RCA). The RCA is sourced from local construction and demolition (C&D) waste in Perth, Australia. The RCA is used as a partial replacement of natural coarse aggregate (NCA) in geopolymer concrete at 15%, 30% and 50% by wt. which corresponds to series two, three and four

It was reported that the sorptivity of air-cured fly ash concrete, cured for 28, 90 and 180 days, increases with an increase in fly ash content. By normal concrete has been shown that the condensed silica fume, under normal curing environments, both increases strength and reduces sorptivity [10].
