In countries where the climate is favorable, green blocks are moist cured at normal temperature of 20°C to 37°C (as in the South of China). This type of curing which at 4 days would normally give 40% of its ultimate strength. Initially, green blocks should be placed in a shaded area or enclosed chambers for about 8-12 hours (depends on relative weather conditions i.e. temperature, humidity etc). After that, the blocks can be transported to an assembly yard for further curing for about 28 days to reach 99% of its maximum strength. For optimal final products, the fresh blocks need to be sprinkled daily, for the first 7 days (morning and evening) to maintain the moisture content for higher reactivity of cement with sand.
