Construction methods used for controlling temperature in mass concrete structure

Abstract

The hydration of cement can release a substantial amount of heat that can be problematic in mass concrete structure. This heat of hydration (HH) can produce thermal stresses that can crack the concrete and compromise the integrity of the structure leading to its failure. Throughout the years, different methods have been developed in order to mitigate the negative effects of the HH on mass concrete structures. This study presents a comprehensive review of the previous methods documented in the literature that have been utilized in controlling the temperature rise due to the HH in mass concreting. The reviewed methods were divided into two main categories, namely supplementary material and construction methods. This paper focuses on the different methods of construction that are used to control the temperature rise in mass concrete structures. The paper also presents an analysis of these methods using findings from previous studies.

Simplified Method for Determining Thermal Stresses during the Construction of Massive Monolithic Foundation Slabs

“…The problem associated with the cracking of hardening concrete structures caused by the heat of hydration has long been known. This problem has been around for probably as long as concrete has been used as a building material [8]. During the construction of massive dams, this was especially noticeable in the first days after their concreting [9].…”

Pre-Cooling Concrete System in Massive Concrete Production: Energy Analysis and Refrigerant Replacement

“…Many strategies for controlling the temperature of massive concrete structures are proposed to improve the endurance of massive concrete structures such as desert dams and bridges. Supplementary cementation materials for instance silica fume, fly ash, slag, metakaolin, or opaline rock are added to the concrete to minimize the heat of hydration in concrete constructions [9]. To improve the thermal and mechanical characteristics of concrete, several researchers substituted aggregate with steel slag aggregate [10].…”
