Problems solved by technology

[0007] However, in this method, since the slag ash with a particle size of 1.5mm-10.0mm is used as the aggregate, there are pores of 100μm (0.1mm)-5000μm (5mm) between the aggregate particles, so the water absorption rate or water permeability coefficient is relatively high. , is excellent in water permeability or water retention, but the mechanical strength (bending strength) as a paving material is low, especially, it is not necessarily suitable as a promenade in a park where someone boards a high-grade load when it is used. Paving materials laid on roads, etc.
[0008] In addition, since any of these conventional porous sintered bodies use relatively soft slag ash discharged from coal-fired power plants as the main aggregate component, the wear resistance is insufficient. , It is not suitable as a paving material for road paving and other purposes. In addition, because hydraulic cement is used as the binder of the aggregate, there is a problem that the cement component dissolves slowly during use, and the pavement The problem of the so-called white crystallization phenomenon in which extremely white powdery residues appear on the surface of the material

Embodiment 1-10

[0043] After screening, slag ash (with a water content of about 10 wt %) and slag cement type B and cullet (manufactured by Sanwa Chemical Co., Ltd.) with a particle size of 3 mm or less, which were cut to a particle size of more than 3 mm, was pulverized and produced. , the glass frit with a particle size of 0.6 mm or less cut over 0.6 mm was blended in the ratio shown in Table 1 as a raw material mixture for the porous water-retaining layer.

[0044] The raw material mixture for this porous water-retaining layer is packed into a countercurrent high-speed mixing mixer (Ellich type mixer) according to the ratio shown in Table 1. At first, no added water is added, after mixing, added water is slowly added to make the mixture containing The water content of the water in the molten slag ash was about 15% by weight, and they were thoroughly mixed to obtain a mixture for a porous water-retaining layer.

[0045] In addition, after screening, the porcelain-like ceramics with a partic...

Embodiment 11

[0055] The porous sintered paving material of Example 11 was obtained in the same manner as in Example 6 above, except that slag ash was used with a particle diameter of 3 to 5 mm.

[0056] The obtained porous sintered pavement of Example 11 was evaluated for finding a white crystallization phenomenon while measuring its physical properties as in the case of each of the above-mentioned examples.

[0057] The results are shown in Table 1.

Abstract

Provided is a porous sintered paving material having excellent mechanical strength and resistance to wear as well as excellent water permeability and water holding property and being useful as a heat island phenomenon suppressing measure by providing or bonding it on a wall face, the rooftop, a road surface or the like in various buildings and civil engineering structures and to provide its manufacturing method. This porous sintered paving material has a multilayer structure in which a porous water holding layer constituted using clinker ash as an aggregate composed of the porous sintered paving material obtained by adding water to raw material mixture composed of aggregate, hydraulic cement, and glass powders, mixing and molding them, and baking the obtained moldings and having particle diameter of 7 mm or less and a porous reinforced layer constituted using porcelain ceramic crushed objects having particle diameter of 6 mm or less as aggregate are laminated using the porous reinforced layer as a surface layer. Its manufacturing method is provided.

Description

technical field [0001] The present invention relates to a porous sintered paving material and a method for producing the same, and in particular to a porous sintered paving material which is excellent in water permeability or water retention and is suitable as a countermeasure against the so-called heat island phenomenon, and a method for producing the same. Paving materials are mainly laid or glued on the outside of buildings or civil structures in urban areas such as buildings, roads, and parks, such as the outer walls of buildings, roof platforms, and roofs, and protective walls of expressways, The pavement of the promenade in the park, etc. Background technique [0002] In recent years, the so-called heat island phenomenon in which the temperature in urban areas is higher than that in surrounding areas has been observed, causing various problems in daily life in urban areas, such as heat stroke, crossed eyes or Effects on the human body such as respiratory organ obstruc...
