The Workability and Compressive Strength of Concrete using Textile Mill Sludge and Plasticizerdoi:10.24247/IJCSEIERDAUG20171Harpreet Kaur
This paper re-examines common notions and conventions regarding the compressive strength of concrete in general and of the uniaxial compressive strength of concrete in particular. A distinction is introduced between the strength of the specimen and the strength of the concrete as a material, and the...
The compressive strength of samples after 28 days of curing are 21.16, 21.04 and 17.60 N mn 2. Based on the results of investigation, it was concluded that the quality of concrete produced using locally sourced barites is better than the one made of granites. In addition, our local barite...

The present paper addresses the problem of the design of suitable model concrete mixes for the investigation of the punching strength of post-tensioned concrete flat slabs. A number of alternative experimental approaches ranging from the use of lightweight aggregates to a combination of crushed basalt...
Strength of concrete: The compressive strength, in kilopascals, was measured for concrete blocks from five different batches of concrete, both three and six days after pouring. The data are as follows: Send data to Excel Part:02 Part1of2 ...
aConcrete is strong in compression,but weak in tension:its tenslie strength varies form 8 to 14 percent of its compressive strength.Due to such a low tensile capacity, flexural cracks develop at early stages of loading.In order to prevent such cracks form developing,a concentric or eccentric ...
Compressive strengthTangential stiffnessPrimary crackCrack angleMicrocrackDICIn this study, uniaxial compression tests using cracked concrete with different crack widths and angles were conducted. The purpose of this study is to clarify influence of crack angle on the compressive fracture process and to ...
The results show that partial cement replacement up to 20% produce, higher compressive strengths than control concretes, nevertheless the strength gain is less than 15%. In this paper we propose a model to evaluate the compressive strength of silica fume concrete at any time. The model is ...
Surface texture was the most important aggregate property influencing concrete compressive strength. Because the aggregate strength was generally greater than that of the concrete and differences in the water-absorptive capacities of the aggregates were small, no relationship was found between the strength...
