Abstract

PURPOSE: To obtain a dustless and splashless dry spraying method, by performing dry spray coating after gravels are mixed to pelletized mortar obtained by mixing sand, water, and cement and by granulating the mixture.
CONSTITUTION: Water W1 which is 5W15% of the weight of sand in weight is added to air-dried sand SD, and the sand is mixed in a mixer, and then cement C1 which is about half of the designed mixing amount is added to the sand. After they are mixed well, pellets are formed from the mixture. During the course of pelletization, cement of the remaining half is sprinkled over the pellets, and thus strong pelletized mortar is obtained. This pelletized mortar is carried by a dry sprayer and injection-sprayed after water of the remaining amount of the designed mixing rate dissolving a quick setting agent Ac is added to the mortar near the outlet. Moreover, after this pelletized mortar is mixed with coarse aggregate in a concrete mixer, resulting product is carried by a dry sprayer, and sprayed after water W2 of the remaining amount of the designed mixer rate desolving the quick setting agent Ac is added near the outlet, thus providing a concrete spraying method.
