    2020-6-18  Three concrete mixes were prepared. The first and second mixes were prepared by using crushed basalt aggregates while the third by crushed dolomite aggregate. The grading of aggregate mixtures was kept nearly close to fuller’s curve for all concrete mixes. Their quantities in 1m3 concrete mix based on oven-dry condition are summarized in Table 3. All concrete mixes were designed to have a water-cement ratio of 0.6 and a slump of 100±20 mm. Concrete cubes (150 mm) were cast for each of aggregate type and curing age for the determination of compressive strength. Concrete cylinders (100mm×200 mm) for each of aggregate type were cast, for investigating the alkali resistance of concrete mixes. Two slice of 100 mm in diameter and 50 mm in thickness were cut from the middle portion of each concrete
