Abstract

The addition of polymers in construction is a new tendency and an important step toward the production of structures with better functional properties. This work investigates the addition of polyurea (PU) as a polymeric material in mortars. Polymer mortars were manufactured with the addition of polyurea retained in different sieves (T50 and T100) and different concentrations (2% and 5%). The characterization of the, polyurea (PU)control mortar (PU0%) and manufactured polyurea mortars (PU2%T50, PU5%T50, PU2%T100, and PU5%T100) was conducted by means of morphological analysis, SEM, XRF, TGA, and a compressive strength test of hydraulic mortars. The results show that mortars with polyurea retained in sieve 100 with a particle size of 150 μm exhibit better thermal behavior and a greater resistance to compression with a concentration of 5% polyurea with respect to the other samples. The present work reveals that polyurea retained in sieve 100 can be considered as a polymeric additive for mortars, indicating that it could be a candidate for applications such as construction.

摘要

在建筑中添加聚合物是一种新趋势，也是朝着生产具有更好功能特性的结构迈出的重要一步。这项工作研究了在砂浆中添加聚脲（PU）作为聚合物材料的情况。通过添加保留在不同筛网（T50和T100）且浓度不同（2%和5%）的聚脲来制备聚合物砂浆。通过形态分析、扫描电子显微镜（SEM）、X射线荧光光谱仪（XRF）、热重分析仪（TGA）以及对水工砂浆进行抗压强度测试，对聚脲（PU）对照砂浆（PU0%）和制备的聚脲砂浆（PU2%T50、PU5%T50、PU2%T100和PU5%T100）进行了表征。结果表明，与其他样品相比，保留在100目筛网（粒径为150μm）且聚脲浓度为5%的砂浆具有更好的热性能和更高的抗压强度。目前的研究表明，保留在100目筛网的聚脲可被视为砂浆的聚合物添加剂，这表明它可能是建筑等应用的候选材料。
