Researchers are studying how building materials can be made in a way that is less energy intensive and can result in cost savings. One such building material is concrete, which is used to make sidewalks and roads, among other structures. Concrete consists of cement, water, sand, and stones that are mixed together. When cement is mixed with water, i

This Tech Brief presents an overview of permeable interlocking concrete pavement (PICP) and its use. General information is provided on PICP composition with a summary of benefits, limitations, and characteristics. Important considerations, such as hydrologic design, structural design, construction, and maintenance, are also provided.
Electrical resistivity is a property that indicates the material’s resistance to the passage of electrical charges at a defined temperature. In concrete, resistivity is directly proportional to the resistivity of the pore solution, and inversely proportional to the volume and connectivity of the pores. Formation factor is the ratio of concrete resi
