Concrete material for greening
TLDR
In this article, a concrete material for greening is defined, which consists of a concrete having cement and an aggregate compounded therein and, added thereto as a granular filler or a powdery additive, a silica based mineral being excellent in water absorbing property, water holding property and the like.Abstract:
A concrete material for greening, which comprises a concrete material having cement and an aggregate compounded therein and, added thereto as a granular filler or a powdery additive, a silica based mineral being excellent in water absorbing property, water holding property and the like. Silica based minerals include diatomaceous earth, pearlite and other minerals containing a major amount of silica. As the aggregate, an ordinary aggregate such as crushed stones or ballast can be used. The aggregate may be used together with the above silica based filler. A light, porous concrete material can be produced by using only lightweight aggregates such as diatomaceous earth and pearlite. One or more of fibrous materials prepared by crushing bamboo, coconuts and wood material and the like and plant fiber materials such as those from Peat Moss can be added as water holding aids for supplementing the water holding property of concrete.read more

TL;DR: In this article, the authors propose to use weakly anionic water-absorptive resins such as the crosslinked matter of the independent polymer of N-vinyl carboxylic acid amide, such as Nvinyl acetoamide, or copolymers with >= 1 kind of (non)ionic monomers, etc., and nonionic water absorbing resins into the gaps of the porous concrete 1 bonded with cement in such a manner that the aggregate 2 such as pebblelike materials and crushed stones, constitute porous bodies.
