(一)

某建筑工程，建筑面积23824 m²，地上10层，地下2层(地下水位-2.0m)。主体结构为非预应力现浇混凝土框架-剪力墙结构(柱网为9m×9m，局部柱距为6m)，梁模板起拱高度分别为20mm、12mm。抗震设防烈度7度。梁、柱受力钢筋为HRB335，接头采用挤压连接。结构主体地下室外墙采用P8防水混凝土浇筑，墙厚250mm，钢筋净距60mm，混凝土为商品混凝土。一、二层柱混凝土强度等级为C40，以上各层柱为C30。

在工程施工中发生了如下事件：

事件一：钢筋工程施工时，发现梁、柱钢筋的挤压接头有位于梁、柱端箍筋加密区的情况。在现场留取接头试件样本时，是以同一层每600个为一验收批，并按规定抽取试件样本进行合格性检验。

事件二：结构主体地下室外墙防水混凝土浇筑过程中，现场对粗骨料的最大粒径进行了检测，检测结果为40mm。

事件三：该工程混凝土结构子分部工程完工后，项目经理部提前按验收合格的标准进行了自查。

问 题

该工程梁模板的起拱高度是否正确说明理由。模板拆除时，混凝土强度应满足什么要求？
