The common concrete mix is comprised of aggregate, water, sand, various chemical admixtures, and portland cement. The primary function of portland cement in the mix design is to create a binding agency which allows these various ingredients to become concrete.
Other systems use the rigid insulation board in the center of the concrete wall. These are often referred to as "tiltwall" construction. The walls are poured in a form on a flat deck and after curing are tilted upright into position by a crane.
Similar to the cob method, rammed earth houses are constructed from a damp soil mixture with specific proportions of clay, sand and gravel. The composition of the soil is important, and you can't use .
Pervious concrete is a porous mix of carefully controlled amounts of water and cementitious materials that forms a paste and forms a thick coating around aggregate particles. As a paving material, it captures storm water and runoff, allowing it to seep into the ground.
