“…Fig. 3 in Section 3 illustrated that after the casting of the three target beams and the concrete cubes, Hangzhou had experienced a sudden drop in temperature, which could adversely affect cement hydration in concrete and thereby led to a slow strength gain for all the three concrete groups [28,29].…”

“…Several examples [3][4][5][6][7][8][9][10][11] about the influence of temperature and curing time of concrete and mortar have been reported. The expected behavior by lowering the curing temperature for the mortars compared to those cured at 20° C, is a reduction of strength in the early ages of curing, maintaining or decreasing slightly at longer curing times.…”

ABSTRACT:Hydration processes in cement pastes and mortars both with the addition of silicoaluminous pozzolans (metakaolin MK and catalyst used in catalytic cracking FCC) have been studied in this paper. Additionally, the amount of hydrates and portlandite in cured pastes from 5 to 20° C and for 3 to 28 days curing time has been determined. The microstructural study by using thermogravimetric analysis in pastes has shown that, at low temperatures (5-10°C) the FCC acts mainly as a pozzolan, whereas MK also produces acceleration in the hydration of cement. The influence from the mechanical point of view is a relative increase in the compressive mechanical strength of mortars cured at 5° C for both pozzolanic materials, through replacement of cement and through replacement of aggregate. These two pozzolans are effective materials to compensate for setting and curing conditions at low temperatures, especially in aggregate replacement mortars.

“…At 14 d and 28 d there was not much difference between water curing and steam curing. This is because only high early-age strength is achieved with steam curing: the strength at later ages is the same as for standard curing (Husem and Gozutok, 2005;Liu et al, 2005).…”

The effect of accelerated curing and steel fibre volume on ultra-high performance concrete (UHPC) is the focus of this paper. The compressive strength and microstructural properties of UHPC were evaluated under water, steam and heat curing. The results show that heat-cured samples have higher mechanical properties than those undergoing the other curing techniques. Experimental studies were conducted on heat-treated specimens with different steel fibre volumes and aspect ratios (2 . 5% and 2 . 0% of 13 mm and 6 mm length fibres of diameter 0 . 16 mm) to examine stress-strain behaviour, tensile behaviour and flexure behaviour. The stress-strain behaviour of UHPC was evaluated by uniaxial compression tests on cylinders to propose a new stress-strain model for UHPC under compression. Size-dependent and size-independent fracture energies were determined as per the Rilem procedure and the P-ä tail correction method. Flexural and residual strengths were evaluated under four-point bending.
