Abstract in simplified Chinese:本发明提供防水膜,其不需要可移除之剥离薄片,但其仍黏合至后浇注混凝土且辅助膜至膜重叠处之水密密封。该防水膜包含载体及压敏黏着剂(PSA)层;无机粒子层,其具有部分嵌入该PSA中且平均粒径小于该PSA层之平均厚度之微粒体;及抗潜含奈米二氧化硅涂层,其附接至该等无机粒子之未嵌入部分以防止在该膜卷起或展开时完全嵌入该PSA中,由此辅助毗邻安装之防水膜之重叠部分之间之水密接缝,且由此该水密接缝较佳仅使用结构细化或防水带且不额外使用液体底漆、胶黏剂或其他涂料来达成。
Abstract in simplified Chinese:本发明揭示用于喷涂使混凝土隧道应用防水之膜的方法、组合物及组合物套组。在底涂层施用于隧道中之表面上之后,喷洒涂料组合物以形成膜,且随后抵靠该膜浇筑或喷洒混凝土以使得其可黏结至膜。涂料组合物包含两种或更多种丙烯酸酯单体以及引发剂、加速剂及视情况存在之添加剂。较佳地,借由使用两部分套组创建涂料组合物,一部分具有引发剂,另一部分具有加速剂,且各部分含有单体及视情况选用之添加剂,从而使得可运送两个部分至施用位点且在喷洒期间以1:1比率混合。防水涂料组合物提供与混凝土之极佳黏结。
Abstract:
A paste composition, method of use, and building product containing such composition. The composition comprises at least one (preferably two) silyl-terminated polymer resin and a plurality of adhesion promoters. In preferred embodiments, the composition has a paste consistency. In preferred embodiments the paste has a slump between 0 and 20 mm, more preferably a slump between 0 and 10 mm, and most preferably a slump between 0 and 5 mm, and a low water absorption after water immersion. In further exemplary embodiments, the composition further has good bond to dry/damp concrete and other substrates, with and without water immersion.
Abstract:
The present invention allows for better control over strength in concrete mixes and mix designs, while minimizing the over-use of cement and promoting sustainability within the industry. Disclosed are novel method and system which employ a diagnostic delta data (DDD) curve, or, in other words, data that displays a curvilinear relationship when plotted on a visual graph, as obtained by considering the differences (e.g., subtractive differences or ratios) as between (i) target slump and target (or maximum) water content, and (ii) slump and water content values as determined using an automated slump monitoring system which measures slump and water content in the concrete mix during delivery. This DDD curve can then be compared to monitored delta slump and delta water content for later or other deliveries, such that adjustments can be made to the concrete mix or mix design, in a manner that encourages avoidance of cement over-dosing or over-prescription.
Abstract:
The present invention relates to modification of hydratable cement and cementitious materials, such as mortar cement and masonry or ready-mix concrete using ketone alcohol oil waste ("KAOW") material, obtained as an alkali-soluble liquor waste byproduct at a certain stage in the commercial production of cyclohexanol and cyclohexanone. Preferred applications for KAOW are in chemical admixture formulations whereby KAOW is used to substitute for a portion of a cement dispersant such as sodium lignosulfonate, sodium gluconate, or other conventional dispersant. Another preferred use is in mortar cement and masonry concrete units such as blocks, pavers, curbstones, and other concrete masonry units wherein air void systems advantageously foster freeze-thaw durability.
