Concrete in farm buildings is subjected to severe corrosion if manure is stored below slatted floors. Many chemicals associated with manure are identified as having a detrimental effect on concrete and the reinforcing steel embedded in... more
... In addition, waste glass seemed to positively contribute to the mortar micro-structural properties resulting in an evident improvement of its mechanical performance [Corinaldesi et al. 2005a]. Mixed colored glass can be utilized in... more
Reactive Powder Concrete (RPC) is a type of ultra-high performance cement based composite with high strength and ductility. RPC was developed in the 1990s by Bouygues' laboratory in France. It is a special type of concrete which has... more
The electrochemical behaviour of reinforcing steel in plain and blended cement concrete specimens placed in sulphate, chloride and sulphate-chloride environments was investigated. The effect of cement composition and the exposure... more
Bioactive glasses have attracted considerable interest in recent years, due to their technological application, especially in biomaterials research. Differential scanning calorimetry (DSC) has been used in the study of the crystallization... more
The present work is performed for the manufacturing of bricks or building block from sand, saw dust and waste plastic. The bricks or building blocks are manufactured by mixing m- sand, saw dust and waste plastic by heating at 200 oc. It... more
The current trend to decrease the clinker content in cements through the use of mineral additions in order to limit CO2 emissions into the atmosphere is of major concern for the precast industry as the resulting binders are generally not... more
The world nowadays is trying to find alternative approaches to be used in manufacturing instead of consuming raw materials. Using recycled aggregates in new concrete is one of these effective approaches, which in turn reduces the quantity... more
This paper reports results of a study conducted to evaluate the effect of silica fume on the compressive strength and split tensile strength and modulus of elasticity of low quality coarse aggregate concrete. Concrete specimens were... more
Abstract: Ultra high performance concrete (UHPC), even though a construction material with excellent performance is deemed to be unsustainable as per many opinions owing to its high cement content which raises the cost and pollution. This... more
The usage of an extensive group of industrial mineral residues (silica fume and fly ash) and other products significantly increases the rheological performance of concrete. This research is supposed to take a look at Rheology and... more
High Performance Concrete can be considered as a logical development of cement concrete in which the ingredients are proportioned and selected to contribute efficiently to the various properties of cement concrete in fresh as well as in... more
A mathematical model is presented for estimating compressive strength of high-strength concrete incorporating pozzolanic materials, based on the strength of a control ordinary Portland cement (OPC) concrete made with similar mixture... more
Abstract: An Engineered Cementitious composite is an ultra ductile cementitious composite which is highly crack resistant, with a tensile strain capacity over that of normal concrete. Engineered Cementitious Composites is similar to Fiber... more
Critical issues and Potential development for Chemical and Metallurgical Industry of Silicon
The packing characteristics of the cementitious materials have great influence on the performance of a concrete mix, but there is so far no generally accepted method of measurement. Herein, a new method, called the wet packing method, is... more
Concrete is one of the most widely used construction materials in the world. However, the production of portland cement, an essential constituent of concrete, leads to the release of significant amount of CO2, a greenhouse gas; one ton of... more
