Sand cone test is detemination of silt content of sand
Choose the grade of concrete & assume minimum water/cement ratio.Conduct some initial tests on the materials like cement, sand & metal(coarse aggregate).Tests like UNIT WEGHT, SPECIFIC GRAVITY,SIEVE ANALYSIS,SLUMP CONE TEST & COMPACTION FACTOR TEST. According to the obtained results do the mix design from IS CODE of IS800-10262 check for water cement ratio & calculate the quantity of cement, sand & coarse aggregate.
mortar mix may be used as a strengthen agent for the available soft soils, it will increase shear strength, but in the same time bonding with aggregate will be decrease. it may consider as a soil stabilization method if cement added as 10% by weight of the sand silty clay. it will work good.
