For % quarry dust concrete workability is . and for % replacement of quarry dust concrete . compacting factor was observed. (d) e compressive strength results of quarry dust concrete (cubes) were obtained in the fourth series, where M, M, and M grades of concrete with,, andThe obtained result shows higher compressive strength in 28 days curing period compare to 7-days curing. . The average compressive strength of concrete cubes for 10% quarry dust is 24.37 MPa at 7 days, which then increased to 34.82 MPa at 28 days. For 20%, the compressive strength develops from 25.32 MPa at 7 days to 35.67 MPa at 28.

Development of Mathematical Models for Compressive

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- 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. · 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… · 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.

[PDF] COMPRESSIVE STRENGTH OF CONCRETE USING …

S Shetty, ). The compressive strength of concrete from stone powder showed 14.76% higher value than that of the concrete made of normal sand (Mahzuz et al., ). It is found that the compressive and flexural strength of concrete made of Quarry Rock Dust are nearly 10% more than the conventional concrete (Suribabu et al., ). In the presentABSTRACT-The purpose of this work is to describe the effect of quarry dust and dolomite on the compressive strength of concrete. The present examinations indicate that dolomite may be used as partial replacement of cement in concrete and quarry dust may be suitably replaced with fine aggregate in concrete to some extent.Samples of concrete (eg. cubes) were made using varying contents of laterite and quarry dust as fine aggregate. The quantity of laterite was varied from 0% to against quarry dust at intervals of 25%. The samples were cured for specified periods and tested in the laboratory for compressive strength.
