Although research has shown a considerable influence of the pre-cracking phenomenon on steel-congested concrete members, only normal (NC) been considered in literature. The intention this paper is thus to study effect bond response pre-cracked NC with different slump flow values and self-consolidating (SCC). Initial crack widths ranging from 0.0 0.5 mm are studied. Results show that initial lar...

This paper presents the results of an experimental investigation carried out to evaluate the shrinkage of High Strength Concrete. High Strength Concrete is made by partially replacement of cement by flyash and silica fume. The shrinkage of High Strength Concrete has been studied using the different types of coarse and fine aggregates i.e. Sandstone and Granite of 12.5 mm size and Yamuna and Bad...

Demand for fresh water by the construction sector is expected to increase due to the high increase in the growth of construction activities in Jordan. This study aims to evaluate the potential of scale-up of the application of treated domestic wastewater in concrete from bench-scale to a full-scale. On the lab scale, concrete and mortar mixes using Primary and Secondary Treated Wastewater (PTW,...

National Institute of Standards and Technology, Gaithersburg, MD 20899-0001 The rheological or flow properties of concrete in general and of high performance concrete (HPC) in particular, are important because many factors such as ease of placement, consolidation, durability, and strength depend on the flow properties. Concrete that is not properly consolidated may have defects, such as honeyco...

A modern lifestyle, alongside the advancement of technology has led to an increase in the amount and type of waste being generated, leading to a waste disposal crisis. This study tackles the problem of the waste that is generated from construction fields, such as demolished concrete, glass, and plastic. In order to dispose of or at least reduce the accumulation of certain kinds of waste, it has...

Submitted: Jul 2, 2013; Accepted: Aug 18, 2013; Published: Aug 29, 2013 Abstract: Experimental Studies were conducted to analyse the influence of crimped polypropylene fibres in cementitious matrix. The compressive strength of concrete with the addition crimped polypropylene fibres for relative volume fractions of 0.1% and 0.3% were evaluated in concrete with water cement ratio as low as 0.3.
