EFFECT OF CURING METHODS ON THE COMPRESSIVE STRENGTH OF CONCRETE T. James, A. Malachi, E.W. Gadzama, V. Anametem oka Department of Civil Engineering, Federal University of Technology Yola, Nigeria. aEmail: [email protected] (corresponding author). Abstract Di erent curing methods are usually adopted to evaluate the compressive strength of concrete.
This paper studied the effect of aggregate properties on the crushing strength of concrete. In order to achieve the study objective, three types of coarse aggregates, brick khoa, shingles stone, and black stone were used to test. And the test results show that concrete made from black stone has the highest workability followed by shingles stone & brick khoa of aggregates.
The best and most accurate method to determine compressive strength of existing concrete is coring. Rebars always make difficulty in coring of reinforced concrete structures. Sometimes it is not possible to core from plain concrete areas. There are serious considerations for effects of rebar on compressive strength of concrete cores in some ...
cement, slump test, compressive strength test, compaction factor test of concrete. Following the above procedures and depending on the age of crusher screen comparative study shall be done to know the affect of age of crusher screen on properties of concrete.
Effect of aggregate type on Compressive strength of concrete Abdullahi. M International Journal of Civil and Structural Engineering Volume 2 Issue 3 2012 794 (Olanipekun, Olusola, and Ata 2006; Neville, 1995). This further buttresses the point that the aggregates can be used for construction work.

Effect of Aggregate Properties on the Crushing Strength of Concrete. International Journal of Materials Science and Applications. Vol. 4, No. 5, 2015, pp. 343-349. doi: 10.11648/j.ijmsa.20150405.19 Abstract: This paper studied the effect of aggregate properties on the crushing strength of concrete…
In this paper we investigate the influence of the shape and of the size of the specimens on the compressive strength of high-strength concrete. We use cylinders and cubes of different sizes for performing stable stress–strain tests. The tests were performed at a single axial strain rate, 10 − 6 s − 1. This value was kept constant ...

Thus, the SPH method is used to establish an abrasive water jet crushing concrete model to study the effect of abrasive concentration on the impact force, concrete internal energy, abrasive particle distribution, crushing depth, and damage and crushing efficiencies under different concrete compressive strengths and abrasive densities.
May 13, 2017· The Compressive strength test will result in a compressive load on the cube and the cylinder during the test procedure. This process will result in the Lateral Expansion of the sample which will result in the Poisson's ratio effect. The figure-1 below shows the compressive …
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.
compressive strength, 38% of the concrete cubes made from sand with varying sand impurities failed to meet the design strength of 25 MPa at the age of 28 days [7]. The effect of the addition of fines to normal-strength concrete at levels of up to 227 kg/m3 was studied in concrete mixtures prepared with constant workability (Katz & Baum, 2006).
