A Comparative Study of M10 and M15 Concrete's Strength Using Hand Mixing Method & Machine Mixing Method

Abstract

The concrete cylindrical compression test was used in our studies of compressive strength tests as a partial replacement for fine aggregate. M10 concrete mix has a cement, fine aggregate and coarse aggregate ratio of 1:3:6, whereas M15 has a cement, fine aggregate and coarse aggregate ratio of 1:2:4. Both Hand Mixing and Machine Mixing have been utilized in the production of concrete cylinders, and both M10 and M15 ratios have been achieved. When making concrete, it is common practice to mix the components by hand rather than using a mixer machine. Concrete mixing without a mixer is reserved for low-volume projects when both the quantity of concrete needed and the need of a consistent mix are minimal. Machine mixing refers to combining the concrete materials in a concrete mixer. We began by sieving fine aggregates (sand) and course aggregates (stone chips). The slam test was then performed by mixing M10 and M15 concrete by hand and machine. We ended up making 36 concrete cylinders in total. On the UTM machine, we tested the compressive strength of those concrete cylinders. Experiment were done to analyze the compressive strength of M10 and M15 concrete using hand mixing method and machine mixing method. Also, we compare compressive strength of M10 and M15 Concrete between hand mixing and machine mixing method. The Highest Compressive strength achieved by Hand Mixing method for M10 4.46 N/mm2 at 28 days. Study result reveals that highest Compressive strength achieved by Machine Mixing method for M10 9.29 N/mm2 at 28 days, the Highest Compressive strength achieved by Hand Mixing method for M15 4.46 N/mm2 at 28 days, the Highest Compressive strength achieved by Machine Mixing method for M15 9.55 N/mm2 at 28 days.
