Jayaraman et al., [4] studied the compressive and tensile strength of concrete using lateritic sand and lime stone filler as fine aggregate. The concrete are made using varying contents of lateritic and lime stone filler as fine aggregate. The quantity of laterite is varied from 0% to against lime stone filler at intervals of 25%.

Calculation of Compressive Strength of Concrete Core. Calculate the compressive test of the specimen using the computed cross sectional area based on average diameter of the specimen. If the L/D ratio is 1.75 or less, correct the result obtained by multiplying with correction factors as given below:
May 18, 2018· Concrete being the major consumable material after water makes it quite inquisitive in its nature. The strength of concrete is majorly derived from aggregates, where-as cement and sand contribute binding and workability along with flowability to concrete.. This is an in-depth article on Compressive Strength of Concrete.

This research paper is for the purpose of disseminating the results of an investigation into the effect of water cement ratio of 0.5, 0.55 and 0.6 separately while producing most commonly practiced concrete of cement, fine aggregate and coarse by 1:2:4 mixtures. This research study is limited to the use of newly grade 42.5R Portland cement that is being produced in Nigeria recently and of ...
Compressive strength of concrete Blocks or concrete masonry units are required to know the suitability of these in construction works for various purposes. Concrete masonry blocks are generally made of cement, aggregate and water. Which are usually rectangular and are used in .
This paper is part of a study investigating the structural characteristics of concrete using various combinations of lateritic sand and quarry dust as complete replacement for conventional river sand fine aggregate. Samples of concrete (eg. cubes) were made using varying contents of laterite and quarry dust as fine aggregate.
effect on the compressive strength of the lateritic concrete mixes. This is in contrast to the performance of the concrete mixes which shows consistent decrease of compressive strength in water-cement ratio. Also, the degrees of workability of both concrete mixes were investigated using slump test.
This paper presents an experimental study on workability and compressive strength of concrete using various combinations of lateritic sand and quarry sand as complete replacement for conventional river sand fine aggregate. Quantity of lateritic sand varied from 0 .
These two issues would require to be addressed sand giving higher strength at 50% replacement. if the material is to be used with assurance. Key Words: Concrete, quarry dust, river sand, Utilization of quarry dust in concrete is recommended compressive strength.
Jan 01, 2012· Ukpata et al [4] investigated the workability and compressive strength of concrete using varying combinations of lateritic sand and quarry dust as complete replacement for river sand. ...
compressive strength of concrete using lateritic sand and quarry dust as fine aggregate up to 28 days of casting concrete. The three models are shown in Table-1 below with their coefficients of determination (R2).
Apr 09, 2015· The compressive strength and tensile strength of concrete using lateritic sand lime stone filler are measured in the laboratory. Compressive strength and tensile strength is found to .
This paper presents an experimental study on workability and compressive strength of concrete using various combinations of lateritic sand and quarry sand as complete replacement for conventional river sand fine aggregate. Quantity of lateritic sand varied from 0 .
Compressive strength of concrete. The compressive strength of concrete is defined as the maximum crushing stress can withstand by the concrete. You may aware of concrete cube test, but you may have some question like why this test conducting or any other question. We listed out the common doubt happening in concrete cube test.
those of conventional concrete. The concrete was found to be suitable for use as structural members for buildings and related structures, where laterite content did not exceed 50%. Index Terms: compressive strength, lateritic sand, lime stone filler and tensile strength
characterise the soils. Classification of the lateritic soil samples within Ota, revealed that the lateritic soils are mostly sandy clay of high plasticity and may replace sand by up to 20%, though an approximate linear decrease in strength with increasing sand replacement with lateritic soil was observed. This percentage replacement can be
4. [5]According to the value of compressive strength collected, the value is high and it show that quarry dust suitable to use as sand replacement. All the value of compressive strength surpasses the minimum value of compressive strength for normal concrete that is 7N/mm . So, quarry dust can apply as sand replacement in
By the replacement of silica sand in concrete, the compressive strength was decreases up to 30% replacement and then ... "Compressive strength of concrete using lateritic sand and quarry dust as fine aggregate" APRN journal of engineering and Applied science, 2012, Pg. No. 81 to 92.
for normal concrete (concrete with river sand as fine aggregate). Keywords: concrete, flexural strength, tensile strength, lateritic sand, quarry dust. 1. INTRODUCTION Concrete is probably the most common material used in the construction industry in Nigeria and most countries of the world. The use of concrete structural
maximum percentage of sand can replace with lateritic soil and manufactured sand for both M20 grade concrete. Concrete mixes containing 0,10,20,30, 40% sand replacement levels were cast, with super plasticizer. Split tensile strength, compressive strength test and flexural strength were
