TL;DR: A pervious concrete product and method of formation, distribution and placing of the same which includes the pre-mixing of a predetermined quantity of cement and water, utilizing what may be defined as high energy techniques to accomplish a predetermined degree of hydration of the cement particles prior to the mixing of the resulting cementitious material batch with aggregate having a predetermined particle size so as to accomplish voids of a sufficient degree in the overall resulting concrete product as discussed by the authors.
Abstract: A pervious concrete product and method of formation, distribution and placing of the same which includes the pre-mixing of a predetermined quantity of cement and water, utilizing what may be defined as high energy techniques to accomplish a predetermined degree of hydration of the cement particles prior to the mixing of the resulting cementitious material batch with aggregate having a predetermined particle size so as to accomplish voids of a sufficient degree in the overall resulting concrete product. The concrete product is transported by suitable means which are mounted on and perform as part of a distributing, placing and finishing unit, developed to provide a uniform, durable and substantially planer surface to the final use of the concrete product.
