    Abstract: A gypsum board having mold resistance includes a gypsum core and gypsum board paper covering two surfaces of the gypsum core. The gypsum core contains first and second anti-mold agents, each having a water solubility of 200 ppm or less, and a waterproofing agent. A mixture consisting of the first and second anti-mold agents and starch is applied on a surface of the gypsum board paper, which surface is out of contact with the gypsum core. The first anti-mold agent is 2-(4-thiazolyl)-benzimidazole (TBZ) or 2-benzimidazol carbamic acid methyl ester (BCM), and the second anti-mold agent is 3-iodo-2-propyl butyl carbamate (IPBC). The total amount of the first and second anti-mold agents contained in the gypsum core is 0.03% to 0.2% of gypsum forming the gypsum core on an active ingredient basis, and the additive amount of the waterproofing agent is 0.3% to 1.5% of the gypsum forming the gypsum core.

    Abstract: Methods of reducing hydroxyl ions in concrete pore solutions are provided. Such methods are useful in providing resistance to gels which form in concrete due to the alkali-silica (ASR) reaction. The methods comprise adding a salt or mixture thereof to the concrete, in aqueous or solid form, the salt or salt mixture having cations higher in valence than the anions. The methods also comprise adding an acidic phosphate or a silicon-containing alkoxide to the concrete. The methods further comprise resisting and/or inhibiting ASR in airfield runway concrete pore solutions by applying a soluble salt or a mixture of soluble salts in solution or a deicing salt mixture in situ to the runway concrete. All of the above methods are useful in reducing hydroxyl ions in concrete. Such methods can be used to resist ASR in fresh concrete, in concrete that is setting, or in hardened concrete.

    Abstract: A method for sealing or resealing a masonry surface in a swimming pool. In a new pool, spa, or similar structure, the masonry surface is cleaned and prepped. A diluted mixture of silicone sealant is then applied to the surface. Staining dyes are optionally added to the sealing formulation. In the case of an old pool, voids and cracks are sealed with a filler. The diluted mixture of silicone sealant is then applied over the old plaster and the filler materials to reseal the surface. Staining dyes may be optionally added to this application of the inventive method as well. A second formulation of the sealant can be used to affix and grout tiles in order to seal all or part of a pool's wall surface.

Such methods are useful in providing resistance to gels which form in concrete due to the alkali-silica (ASR) reaction. The methods comprise, in one aspect, adding a salt to the concrete, in aqueous or solid form, the salt having a cation higher in valence than the anion. In other aspects, the methods of the present invention comprise adding an acidic phosphate or a silicon-containing alkoxide to the concrete.
