A study of suitability of Dacca clays for light-weight aggregate production in East Pakistan

The following report covers field work and muffle furnace tests on clays in the immediate vicinity of Dacca, East Pakistan, to determine clay amenability to bloating for the commercial production of light-weight aggregates. It has been established that such clays exist in at least three areas; reserves are sufficient in each area for 20 years or more of operation of a light-weight aggregate plant, if the plant were designed to produce 1,000 cubic yards of expanded material per day for 330 operating days per year. Reserves in any of the three areas can be expanded further or new deposits can be found by additional exploratory work.
