Abstract
The development of irrigation installation in paddy field combined with the improvement of ecology is one of the important elements of agricultural water technology. On the basis of the previous literatures, significant works have been performed on designing agricultural waterway sand investigating ecology stability for demonstrating place. In spite of the importance of the modern irrigation engineering in the agricultural waterways, less attention has been paid to the materials of the construction process. In fact, the development of high functional nature materials is also greatly required for the purpose on improving potential functionality of irrigation installation in paddy field. In our study, a novel ecological material was fabricated by using intrinsic porosity concrete as basic element. The porosity of the ecological concrete is expected to enhance plant growth and water recharge. Several additives such as oyster-shell powders or diatomites are added into the porosity concrete to promote the benefit functions of the ecological material. The use of these additives would solve environmental problem in the disposal of the waste, and deal with the problem of insufficient natural material while implementing the natural works in irrigation engineering. Additionally, poly (acrylic acid) polymers are also use for humectants due to their excellent water absorption. After the molding process of manufacturing the concrete blends pre-cast slabs, we will study the physical properties of the new ecological building boards, and estimated their usability in agricultural waterways. The novel materials have benefits of the ecological property, construction convenience, and economic effect.
