No Fine Concrete
Abstract: No-fine concrete has been in use in many countries over more than a century. Its higher porosity helps in percolating rain water directly to ground and thereby helps in recharging groundwater aquifer. In this study, 3 batches of no-fine concrete each with two different sizes of aggregate were prepared to find the mix that generated high compressive strength and study the effect of percentage of fine aggregate on the compressive …

Effect of Accelerated Curing and Normal Curing Regimes on UFGGBFS-Based Semi-Lightweight Concrete
Abstract: This paper deals with the performance of semi-lightweight concrete (sLWC), prepared by using calcite powder pellets as coarse aggregates which was improved by partial replacement of cement with UFGGBFS (ultrafine ground granulated blast-furnace slag). Cement could be replaced by UFGGBFS as 0%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, and 70% to enhance the strength and durability properties of concrete.

A Study on Self Compacting Concrete using Portland Pozzolana Cement
Abstract: Self-compacting concrete (SCC) is a type of highly flowable concrete that fills each and every corner of congested formwork without the need for mechanical vibration as it is placed by means of its own weight. Generally, the SCC is prepared by using Ordinary Portland Cement (OPC) with mineral and chemical admixtures. Portland Pozzolana Cement (PPC) itself contains some amount of fly ash, thus given the motivation to prepare the SCC …

Evaluation of The Resistance of Concrete by Partial Replacement of Coarse Aggregate with Steel Slag and Cement with Bentonite Powder
Abstract: According to the WHO, concrete is the third most consumed material by humans after food and water. Concrete consists of cement, coarse aggregate, fine aggregate and water. In the production of cement, carbon dioxide is released into the environment, which becomes a big problem for environmental protection. Therefore, there is a need to modify the cement with some natural materials with pozzolanic properties. The aggregates, which are extracted from natural …

Review on segregation resistance of self compacting concrete
Abstract: In order to produce thin precast elements, a self-compacting concrete was prepared. While assembling these components, homogenously scattered steel strands rather than normal steel-building up network were added to the substantial combination at a dose of 10% by mass of concrete. A sufficient substantial strength class was accomplished with a water to solidify proportion of 0.40..Extensive test programs of SCC with differences in water – binder proportions, glue volumes, mixes …

Optimizing Aggregate Gradation for Enhancing Strength Properties of Pervious Concrete
Abstract: Pervious concrete possesses high permeability enabling environmental applications like stormwater recharging. However, lower strength limits widespread infrastructure adoption necessitating enhancements. This study focuses on optimizing aggregate proportions for improving compressive and flexural strength. Mixes were developed with cement variations from 200-500 kg/m3 with fine to coarse aggregates ratios systematically altered. Strengths were measured as per ASTM C39 and ASTM C78. Results showed reduced water-cement ratio and balanced aggregate blends improved …

Compressive Strength and Chloride penetration on Semi-Lightweight Concrete Made Up of Artificial Aggregates
Abstract: This paper deals with the properties of semi-Light weight concrete prepared by using Light weight wood ash pellets as coarse aggregates. It can be prepared by varying the cement content from 300 to 450 kg/m3. Optimum design mix can be finalised by studying the engineering properties such as compressive strength, split tensile strength, young’s modulus and rapid chloride penetration test. Various trial mixes have been attempted in the laboratory by …

Optimization of Compressive Strength of Segmental Interlocking Stones
Abstract: The failure of most segmental interlocking stones used as pavement materials is traceable to lack of knowledge of the mix ratios that would optimize the compressive strength of the end products. In this study, the compressive strength was optimized based on Scheffe’s simplex lattice approach. The reliability of model developed was investigated using F-statistic and was found to be adequate. A computer program written in basic language was used to …

Object Reconstruction Using Phone and Compact Camera
Abstract: Previously, a 3D model can be produced by using high resolution and metric camera in close range photogrammetry technique. In this study, there were two types of camera used; the compact camera (Nikon COOLPIX L120) and phone camera (Samsung Galaxy Note1). Two objects were selected; i.e., a biscuit container as for simulation and water tank as the real object. 3D models for both objects were validated by using a measuring …
