(ASAP PLEASE) Design a concrete mix for the following conditions and constraints using the Absolute Volume Method. The material description are as follows:      I. Design Environment         i. Retaining Wall exposed to moderate sulfate exposure         ii. Required Design Compressive Strength = 27.6 MPa         iii. Standard Deviation of Compressive Strength of 1.8 MPa is expected (25 sample only)         iv. Minimum dimension = 200 mm         v. Minimum space between re-bars = 50 mm         vi. Minimum cover over re-bars = 50 mm         vii. Maximum Slump is required         viii. Only air entrained is allowed      II. Available Materials         i. Air Entrained – Manufacture Specification 5.5ml/1% air/100 kg cement (use maximum or +2% air                content)         ii. Coarse Aggregates                25 mm Nominal Maximum Aggregate Size                Rounded River Gravel (Note: apply water…

What is water cement ratio? Compute the value of water cement ratio in the mix. Answer with 2 decimal places only.

Which of the options are correct for a 3m³ of concrete having design mix proportion of 1:2:7 (by volume) A Volume of cement required = 0.318 m³ B No. of cement bags required = 15 C D Volume of coarse aggregate = 2.5 m³ Volume of water required = 1m³

Note:hand written solution should be avoided.
