A STUDY OF COMPRESSIVE STRENGTH OF CONCRETE USING

Comparing the compressive strength at 28 days between concrete mixing with quarry dust and sand, the maximum compressive strength is 407 ksc for concrete mixing with 70% of quarry dust while the normal concrete has value of 348 ksc. From this research, the quarry dust could be used to replace sand in general concrete structures.

COMPARING THE COMPRESSIVE AND FLEXURAL STRENGTH

Abstract. This study tried to compare the flexural strength of concrete made with riversand and quarry dust as fine aggregate.River sand was collected from Osogbo, Osun State, replaced at 0-100% at intervals of 10% with quarry dust gotten from Wasimi, Osun State, Nigeria.Abstract Common river sand is expensive due to the excessive cost of transportation from natural sources.

Study on Compressive Strength of Quarry Dust as Fine

(c) The compressive strength results of quarry dust concrete (cubes) were obtained in the third series, where M20, M25, and M30 grades of concrete with 20, 25, and 30 percent replacement of quarry dust and also workability are studied by varying the water-cement ratio of 0.45 and 0.50 and the results are presented.

Analysis of Concrete Made from Quarry Dust

cement, fine aggregate, coarse aggregate, quarry dust. The examples were casted for M25 grade of concrete by supplanting the cement 0%, 5%, 10%, 15% and 20% by quarry dust and tested for workability by slump test, compressive strength, flexure strength and split tensile test at the age of 7, 14, 28 and 50 days.

Effect of Quarry Dust on High Performance Concrete

(2003) reported significant increase in compressive strength, modulus of rupture and split tensile strength when 40 percent of sand is replaced by Quarry Rock Dust in concrete. Nagaraj (2000) studied that the consumption of cement content, workability, compressive strength and cost of concrete made with Quarry Rock Dust.

Effect of quarry rock dust on the flexural strength of

Jun 01, 2018· The flexural strength of concrete made with quarry dust as fine aggregate is higher (about 4.3%) than conventional river sand concrete. 2. The 10–15% rule of thumb was found to be applicable in the estimation of flexural strength of quarry-sand concrete based on its compressive strength

Development of Mathematical Models for Compressive

Fresh and hardened concrete properties have been tested on concrete containing natural sand along with quarry dust and waste plastic. An attempt has been made to prepare mathematical models for predicting 14, 28, 90 days compressive strength of concrete. The results have been compared with that of SPSS software.

Models For Predicting The Structural Characteristics Of

The effect of the inclusion of quarry dust in sandcrete block production has been partially addressed by some researchers (Boeck et al. 2000, Oyekan and Kamiyo 2008, Olaniyan et al. 2012, Danso 2005). In their works, it was confirmed that the inclusion of quarry dust did improve the compressive strength, but at varying degrees.

Novel Analytical Method for Mix Design and Performance

Despite extensive in-depth research into high calcium fly ash geopolymer concretes and a number of proposed methods to calculate the mix proportions, no universally applicable method to determine the mix proportions has been developed. This paper uses an artificial neural network (ANN) machine learning toolbox in a MATLAB programming environment together with a Bayesian regularization
