    Abstract: 本發明揭示用於噴塗使混凝土隧道應用防水之膜的方法、組合物及組合物套組。在底塗層施用於隧道中之表面上之後,噴灑塗料組合物以形成膜,且隨後抵靠該膜澆築或噴灑混凝土以使得其可黏結至膜。塗料組合物包含兩種或更多種丙烯酸酯單體以及引發劑、加速劑及視情況存在之添加劑。較佳地,藉由使用兩部分套組建立塗料組合物,一部分具有引發劑,另一部分具有加速劑,且各部分含有單體及視情況選用之添加劑,從而使得可運送兩個部分至施用位點且在噴灑期間以1:1比率混合。防水塗料組合物提供與混凝土之極佳黏結。

    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.
