Cotton and limestone powder wastes as brick material

The wastes are processed to clean the cotton fibres and then it submerged in NaOH and water content in 1 h at 90–95 C heating in first 30 min from 40 to 90 C. Then, the treated and cleaned CW is rinsed with hot water in 30–40 C. This process allowed the CW fibres to homoge-neously mix with limestone and cement–water mixtures.
