ADDITIVE FOR CONCRETE AND METHOD FOR PRODUCING ADDITIVE
PROBLEM TO BE SOLVED: To provide an additive for concrete which can adjust functional expression times of various functional materials, and to provide a method for producing the additive.SOLUTION: There is provided an additive for concrete which has a functional material that contributes to a reaction of concrete, and an alkali-soluble resin layer that covers the functional material, where the functional material is at least one selected from an expansion agent, a thickener, a dispersant, an AE agent, a water-reducing agent, a setting and hardening modifier, a rust-preventive agent, a blowing agent, a foaming agent, a fiber reinforcing agent, a polymer admixture, and a silica admixture accelerator.SELECTED DRAWING: Figure 1
【課題】様々な機能性材料の、機能発現時間を調整可能な、コンクリート用添加剤、及びこの添加剤の製造方法を提供する。【解決手段】コンクリートの反応に寄与する機能性材料と、この機能性材料を被覆するアルカリ可溶性樹脂層とを備える、コンクリート用添加剤。機能性材料が、膨張剤、増粘剤、分散剤、ＡＥ剤、減水剤、凝結・硬化調整剤、防錆剤、発泡剤、起泡剤、繊維質補強剤、ポリマー混和剤、シリカ質混和剤促進剤から選ばれる少なくとも一種である、コンクリート用添加剤。【選択図】 図１
