“…This suggests that concrete microenvironment temperature is much more responsible for temperature effect on concrete durability. The result is in agreement with earlier studies [8][9][13][14][15].  The climate environment temperature rises at a faster rate than the micro-environment temperature from the sunrise time to the maximum temperature some hours after the noon time; and falls faster than the micro-environment temperature through the sunset time to the night period; as a result of change of transmission medium of temperature, and the coupled effect of heat convection, and conduction.…”

“…The diagram revealed lesser temperature difference for the unsheltered environment than the sheltered environment. The finding affirmed the claim that temperature response in unsheltered concrete micro-environment is higher than the sheltered micro-environment as a result of sunshine and daylight effects [8][9]. Nevertheless, relationships amongst temperature difference and temperature range are presented in Figures 8(a The relationship amongst temperature difference and temperature range for the unsheltered concrete and sheltered concrete are explained in ( 4) and ( 5) respectively.…”

“…Figures 2a and 2b revealed that the average temperature within the period of test is 30.48 o C while the difference of the amplitude crest and trough is 15 o C with the daily temperaturerise period of about 8.33 hours. The result showed that value of the difference of the amplitude crest and trough differ by 85.2% compared to the case at Changsha described in [8]. This suggests varying impact of temperature on concrete performance as a result of different degrees of daily temperature fluctuation in the environment.…”

“…Previous studies have shown various ways that temperature influenced concrete deterioration and service life reduction of concrete structures [1][2][3][4][5][6][7]. It has been revealed that the temperature effect on concrete durability was stirred by the concrete micro-environment temperature [3,[8][9][10][11][12][13][14][15]. The submission of previous researchers in [3] showed the relevance of describing the environment parameters in the natural climate and concrete micro-environment based on climate zones.…”

The objective of this paper is to characterize concrete micro-environment temperature response to the natural climate of the tropical rainforest. The peculiar warmth, high humidity, and low pressure nature of the tropical rainforest necessitated the present study. Temperature probes were inserted into concrete specimens subjected to the sheltered and unsheltered environment to measure the micro-environment temperature of the concrete, and study the hysteresis characteristics in relation to the climate temperature. Some mathematical relationships for forecasting the internal temperature of concrete in the tropical rainforest environment were proposed and tested. The proposed relationships were found reliable. It was observed that the micro-environment temperature was lower at the crest, and higher at the trough than the climate environment temperature with a temperature difference of 1-3 oC. Also, temperature response in concrete for the unsheltered micro-environment was 1.85 times faster than the response in the sheltered micro-environment. The findings of the study may be used to assist the durability assessment of concrete.

The safety of geotechnical engineering in cold region depends on the stability of supporting structure. Wet shotcrete technology (WST) has the advantages of less dust on the working surface, low rebound and high strength of shotcrete layer, so it has been gradually applied in roadway support of broken surrounding rock. In the cold environment, the decrease of the curing temperature of WST will have an impact on the development of shotcrete strength, but the influence of this temperature difference has not been fully considered in the current engineering practice. Aiming at the phenomenon of small thickness, low strength, and easy cracking of shotcrete in the application of WST in a mine in alpine environment, the temperature effect study on the strength evolution of WST was carried out. The research puts forward the optimization measures for WST support in the alpine environment, which effectively improves the structural strength of the shotcrete, the support repair rate is greatly reduced, and the support efficiency is significantly improved, it also provides reference for WST construction under similar engineering conditions.
