- aProportion a concrete mix for M30 grade concrete by IS method. Given data: maximum nominal size of aggregate: 20mm; minimum cement content : 340kg/cum; maximum w/c ratio: 0.45; workability: 75mm slump; ex posure: severe; concreting type: Manual; quality at site: good; aggrega te type: angular; Zone of Fine Aggregate II; sp. gr of cement – 3.15, C oarse aggregate – 2.68, Fine aggregate - 2.62 ; Design using IS 10262 – 2019
- bDesign a concrete mix for construction of an elevated water tan k, specified design strength is 30 mpa @ 28 days. The specific gravity of F. A. and C.A. are 2.65 & 2.7 respectively. Zone of fine aggregate is III. OPC ( 4 3 G r a d e ) will be used. A slump of 100mm is necessary. C.A. is found to b e absorptive to extent of 1% and free surface moisture of sand is 2% assume any other data. Exposure condition is moderate(IS 10262-2019)
