67. Properties of Concrete Exposed to Low Temperature Environment at Early CuringHASABA, Shigemasa
Laboratory experiments show a close correlation between the measured permeability index and the duration of curing, curing temperature, type of cement, w/c-ratio and content of fly ash of the concrete. The method is very sensitive to changes in most parameters which affect the pore structure of...
come down, descend, go down, fall - move downward and lower, but not necessarily all the way; "The temperature is going down"; "The barometer is falling"; "The curtain fell on the diva"; "Her hand went up and then fell again" ...
The effect of high-temperature curing at an early age on the strength development of concrete using moderate-heat portland cement was quantitatively studied. High-temperature curing conditions were set so as to give systematic variations in the temperature-time factors. As a result, the integrated ...

aExperimental curing agent, Anquamine 721 offers the benefit of a system which shows good viscosity on dilution with retention of viscosity at low solids for cost effective concrete primer and paint applications. 实验性固化剂, Anquamine 721提供在稀释显示好黏度以黏度保留在低固体为费用有效的具体底漆和...
Summary:This paper summarizes the conclulions drawn from experimental work carried out at the Cement and Concrete Association Research Station and elsewhere concerning the principles underlying steam curing at atmospheric pressure.It is shown that if the temperature gradient of the concrete after the time...
What exactly is the building material of choice at DFCI? Gregg Semenza: real Nobel Prize and unreal research data “Even after people have been telling you for, you know, 20 years or more that it’s going to happen, no one expects it.” -Gregg Semenza, Nobel Prize winner 2019 ...

Introduction Magnesium phosphate cement (MPC) is a new cementitious material prepared by dead burned magnesium oxide (MgO), acid phosphates, chemical additives, and mineral admixtures, and...
These prepared mortar bricks samples were cured for various curing ages at room temperature at 3 days, 7 days, 14 days, and 28 days, separately. In addition, we fabricated self-healing mortar samples containing 5% control burnt bagasse ashes (SHM + 5% C-BA) (Table 1). For the ...
