Updated August 16, 2019. Adobe is essentially a dried mud brick, combining the natural elements of earth, water, and sun. It is an ancient building material usually made with tightly compacted sand, clay, and straw or grass mixed with moisture, formed into bricks, and naturally dried or baked in the sun without an oven or kiln.The kiln is the major energy user in the cement-making process. Energy use in the kiln basically depends on the moisture content of the raw meal. Figure 2 provides an overview of the heat requirements of different kiln types . Most electricity is consumed in the grinding of the raw materials and finished cement.
