Determining in-place properties of modest and mass sized placements can be elusive, especially for ultra-high performance concretes (UHPC) with low water to cementitious materials ratios and high cementitious materials contents. In this paper, test procedures are introduced that allow users to cast, cure, and test laboratory scale specimens to estimate in-place thermal and mechanical properties of modest sized UHPC placements. A set of recommended curing protocols are given to simulate time-temperature profiles of structures with least dimensions up to 0.5 m using 10.2 by 20.3 cm specimens that can be readily cast, cured, and tested. Several modestly sized UHPC placements, ranging from 1:20 to 1:3 scale of a typical mass concrete element, were used as benchmarks for curing protocol development. The curing protocols developed are intended to replicate stagnant, hot air environments such as interior building columns, but they were also shown to provide an approximate thermal profile for placements exposed to some other environmental conditions.

确定中等和大块尺寸的位置的就地特性可能难以捉摸，特别是对于水与胶凝材料比率低和胶凝材料含量高的超高性能混凝土 (UHPC)。在本文中，介绍了测试程序，允许用户铸造、固化和测试实验室规模的样品，以估计中等尺寸 UHPC 放置的就地热和机械性能。给出了一组推荐的固化协议，以使用 10.2 x 20.3 cm 的样品来模拟最小尺寸达 0.5 m 的结构的时间-温度曲线，这些样品可以很容易地浇铸、固化和测试。几个中等大小的 UHPC 放置，从 1:20 到 1:3 比例的典型大体积混凝土元素，被用作固化协议开发的基准。
