• Of all the desirable properties of hardened concrete such as the tensile, compressive, flexural, bond, shear strengths, etc., the compressive strength is the most convenient to measure and is used as the criterion for the overall quality of the hardened concrete (Majid, K.I., 1974).
Ukpata et al  investigated the workability and compressive strength of concrete using varying combinations of lateritic sand and quarry dust as complete replacement for river sand.
proportion applicable for structural use of laterised concrete is 1:1½:3 with a water cement ratio of 0.65. 2.2 Compressive strength of concrete containing laterite Concerning compressive strength of laterised concrete, a statement made by (Nevile, 1995)states that laterised concrete can not give better compressive strength than 10Mpa.
increases. Compressive strength of concrete with lateritic sand and periwinkle shell as partial replacement up to 20% is the highest compared to other percentage replacements irrespective of the curing ages and curing methods. Keywords: Concrete, lateritic, sand, strength, periwinkle shell.
The density and compressive strength of each cube was measured on the 7th and 28th test dates. An increase in slump and compressive strength was observed in the lateritic concrete, as portions of the lateritic gravel were replaced with sand.
The compressive strength of M30 concrete has been tested for 3, 7, 28 days of curing with the percentage of quarry dust varying from 20%, 25% and 30% replacement. ... concrete using lateritic sand ...
Hence, concrete proportion of lateritic sand and quarry dust can be used for construction provided the mixture of lateritic sand content is reserved below 50%. Both flexural strength and tensile strength are increased with increase in lateritic content.
Here metakaolin isused and increase in compressive strength of concrete is determined.Also due to recent development in construction industry there is an increase in the use of river sand which ...
The compressive strength of concrete is about 4000 psi. Definition. Strength of hardened concrete measured by the compression test. The compression strength of concrete is a measure of the concrete's ability to resist loads which tend to compress it.
Jun 13, 2013· compressive strength of concrete using lateritic sand and quarry … lateritic sand and quarry dust as complete replacement for conventional river ….. This indicates great difference between the Calabar …..
Fig 4: Relationship between compressive strength and water/cement ratio for Trial casting. Based on the results of trial castings presented in Table 5 and 6, it is observed that for M. 25. grade concrete W/C 0.48 with 50% conventional sand and 50% lateritic sand resulted in good workability and compressive strength.
This research looks into the possibility of producing a laterized Earth moist Concrete, with the view of determining the compressive strength of Earth Moist Concrete using laterite as partial ...
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
Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes @28 days. Compressive strength of Concrete and its importance:- As we all know that concrete is a mixture of sand, cement, and aggregate .
This paper is part of a study investigating the str uctural characteristics of concrete using various c ombinations of lateritic sand and lime stone filler as complete replacement for criver sand ...
Compressive strength of concrete using lateritic sand . 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.
Key words: Quarry dust, Lateritic sand, Compressive strength, Tensile strength, Flexural strength. 1. INTRODUCTION: A view from past history of the construction industry, river sand has been used as one of the major components of the building materials due to the ready ... The strength of hardened concrete using quarry dust and
suggest that concrete containing mixtures of lateritic sand and quarry dust can be reasonably used in structural elements as for normal concrete (concrete with river sand as fine aggregate). Keywords: concrete, flexural strength, tensile strength, lateritic sand, quarry dust.
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 increase with age as for normal concrete.
Many factors are known to affect the strength and creep properties of laterized concrete prisms. Those considered in this report include: mix proportion, water/cement ratio, curing ages, grain ...
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.
The following conclusions can be drawn from the investigations carried out on the effect of aggregate variation on the compressive strength of lateri- te concrete ; (i) laterite can be used as a substitute for river sand in making concrete since there is not much difference between the laterite concrete and normal concrete, with river sand, 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.
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 …
