Corrosion of reinforced concrete is one of the major problems in the construction industry causing premature deterioration of concrete structures well before their service life. This has placed incredible financial burden on many projects and also placed safety of users at risk. A research work was carried out to evaluate the effect of water cement ratio on corrosion of steel in reinforced conc...

Ceramic waste is most commonly produce from ceramic industry, this waste is in the form of pest and hard form, pest waste is known as the filter waste or slurry waste, which is produced at the end of polishing and finishing of ceramic tiles. The paper discuss that ceramic slurry waste powder is replaced by cement in concrete. Concrete grade M25 was made by replacing by 0% to 30% of Ordinary Por...

Currently, building industry uses non-destructive testing methods primarily for evaluation of concrete quality. Efficiency of ultrasonic pulse method (UPM) was proved in order to determine compressive strength of solid bricks (concrete, calcium silicate and burnt ones). Parameters obtained from UPM testing (such as ultrasonic pulse velocity, dynamic modulus of elasticity) are affected by shape/...

Capacity spectrum procedures developed for the assessment and strengthening of existing buildings have become the basis of methods for estimating potential post-earthquake losses which are today widely used in the insurance industry, and for urban risk mitigation programmes. The areas to which these methods are applied often contain (or largely consist of) reinforced concrete apartment building...

This paper reports on the key features of the “Guide for the Design and Construction of Concrete Reinforced with FRP Bars” issued by the American Concrete Institute (ACI). For new construction, FRP bars have been used as the internal reinforcement in concrete members to replace conventional steel rebars for a host of reasons. The principles for design and construction were first established and...

Research Question: Is the lean production philosophy applicable in precast concrete factories to achieve sustainability? If it is, what are the imperfections that can be improved to achieve sustainability? Purpose: This study aims to identify the contribution of the lean concept to achieve sustainability in precast concrete factories. By using appropriate lean principles, the precast concrete i...

Due to their positive technical properties, such as high chemical resistance and mechanical durability, epoxy resins are moving into more and more deployment areas. Significant applications in the construction industry are coatings for industrial flooring, concrete restoration, corrosion proofing, adhesives for tiles, and joint mortar. Unfortunately, the growing use of these products is also co...

Rapid industrialization results in increased use of natural resources bring along serious ecological and environmental imbalance due to the dumping of industrial wastes. Principles of sustainable construction have to be accepted with regard to the consumption of natural resources and the production of harmful emissions. Cement is a great importance raw material in the building industry and toda...

Concrete sleepers have been widely used throughout the world as an alternative for timber sleepers. In North America, heavy-haul railroads have increased their use of concrete sleepers in recent years for a variety of factors. According to an international survey conducted by researchers at the University of Illinois at Urbana-Champaign (UIUC), railroad industry representatives consider center ...
