How To Check Suitability Of Water For Concrete Mixing? Concrete is a chemically combined mass made of binding materials and inert materials combined with water. Due to its unique durability and reasonable strength, it is the most popular construction material; more interestingly, it can be modified and designed for a wide range of strength requirements and set under a variety of environmental conditions.
Cement is the most important component of concrete, and it is produced at a high cost in terms of CO2 emissions; nearly 900 kg of CO2 is released into the atmosphere to produce one tonne of cement.
To Determine whether water is suitable for use in concrete mixes. OR To assess suitability of water for use in concrete mix.
- Cube Molds
- Measuring cylinder
- Tamping rod
- Testing machine
- Vibrating table
- Analyze the chemical compositions of water according to IS 3025-1964 and compare them to the permissible limits specified in IS 456-2000.
- The suitability of water is tested by making concrete cubes if it does not meet the permissible limits or obtaining chemical analysis data is difficult. Concrete of the desired grade is mixed with available water in the proportions specified, and cubes are cast for testing.
- Make the same concrete mix with distilled water and cast the cubes in the same way you did with unidentified water.
- Cure both samples in the same water and under the same conditions.
- Both cube specimens were tested in the same way after 7 and 28 days. Compare the strength and surface conditions of cubes prepared with available water and distilled water in the test results.
- If the strengths are not significantly lower and no deterioration is observed in concrete prepared with unknown quality available water, it is considered suitable.
- To determine whether water is suitable for mixing and curing concrete, a concrete cube specimen should be prepared and tested under similar conditions with both available water of unknown quality and distilled water.
- In both cases, the proportions of the mixture should be the same.
- All appliances should be in good working order.
- The cement, sand, and coarse aggregate used on site should be the same.
Calculate the average compressive strength of concrete made with unknown water compared to distilled water.
