81 (Download)
Concrete is one of the most important building material and day by day theutilization of concrete is increasing to meet the infrastructure developmentrequirement. On one hand it is unavoidable but some alternative to beexplored to reduce the global environmental impact caused by the concrete.To overcome this from the last decade the world is looking towards...2021-09-13 -
A Carbonation and Chloride Induced Corrosion Model for Hot-dip Galvanised Reinforcement Bar Material in Concrete
13-18
Article ID: 3150
316 (Abstract) 24 (Download)
This paper focuses on methodological issues relevant to corrosion risk prediction models. A model was developed for the prediction of corrosion rates associated with hot-dip galvanised reinforcement bar material in concrete exposed to carbonation and chlorides in outdoor environment. One-year follow-up experiments, over five years, were conducted at various carbonation depths and chloride contents. The...2021-09-18 -
Partial Replacement of Cement by Solid Wastes as New Materials for Green Sustainable Construction Applications
8-12
Article ID: 3082
322 (Abstract) 33 (Download)
The manufacturing of ordinary Portland cement is an energy-intensive process that results in pollution and CO2 emissions, among other issues. There is a need for an environmentally friendly green concrete substitute. Waste products from a variety of sectors can be recycled and used as a green concrete substitute. This decreases the environmental effects of concrete...2021-09-18 -
The Effect of Various Polynaphthalene Sulfonate Based Superplasticizers on the Workability of Reactive Powder Concrete
24-29
Article ID: 2731
1085 (Abstract) 38 (Download)
A superplasticizer is a type of chemical admixture used to alter the workability (viscosity) of fresh concrete. The workability of fresh concrete is often of particular importance when the water-to-cement (w/c) ratio is low and a particular workability is desired. Reactive Powder Concrete (RPC) is a high-strength concrete formulated to provide compressive strengths exceeding...

Properties of Sawdust Concrete
Article ID: 4818
148 (Abstract) 28 (Download)
This work examined the structural properties of concrete obtained bypartially replacing cement with sawdust ash. The sawdust ash which is apozzolan was obtained by burning sawdust which is a waste product fromprocessing of timber in an open air. The burnt ash was passed through a150 µm metric sieve to obtain the ash used. Physical and...2022-09-30 -
Photon and Fast Neutron Transmission Parameters of Metakaolin Doped Concrete
58-66
Article ID: 3817
249 (Abstract) 23 (Download)
Radiation-shielding properties of metakaolin doped concrete samples wereinvestigated in this report. The gamma photon mass attenuation coefficientsand exposure buildup factor of the samples were determined theoreticallyusing WinXcom and EXABCal software respectively for the energyrange of 15 keV - 15 MeV and fast neutron removal cross section for theconcrete sample was evaluated. Results indicated that, oxides...2021-12-06 -
Concrete Mix Design by IS, ACI and BS Methods: A Comparative Analysis
30-33
Article ID: 2636
993 (Abstract) 78 (Download)
Concrete is one of the most consumable construction materials on the earth. The concrete constitutes cement, sand, gravel, water and/or additives in definite proportions. The proportions of raw materials of concrete are decided by the concrete mix design. The mix design depends on the various factors. For mix design, most of the countries have their...

Feasibility Study on Use of Plastic Waste as Fine Aggregate in Concrete Mixes
26-31
Article ID: 1204
230 (Abstract) 36 (Download)
Plastic is used in many forms in day-to-day life. Since Plastic is non-biodegradable, landfills do not provide an environment friendly solution. Hence, there is strong need to utilize waste plastic. This creates a large quantity of garbage every day which is unhealthy and pollutes the...

Impact of Polymer Coating on the Flexural Strength and Deflection Characteristics of Fiber-Reinforced Concrete Beams
Article ID: 5304
107 (Abstract) 7 (Download)
Liquid polymers (LP) have become an important structural material used in the construction industry in the last decade. This paper investigates the viability of using commercially available LPs as a coating material to improve the flexural strength of fiber-modified concrete beams. The scope included preparing rectangular prism concrete beams with a concrete mixture including fly...

Assessing the Ageing Impact on Fatigue Life of Asphalt Concrete
9-15
Article ID: 2792
976 (Abstract) 24 (Download)
The fatigue life of asphalt concrete is often related to environmental condition, loading condition, ageing, material composition and properties. This work investigates the influence of short and long term ageing of laboratory beam specimens, asphalt content, and testing temperature on fatigue life of asphalt concrete wearing course. Slab samples of (30 x 40x 6) cm...
