Abstract:

This paper discusses winter curing of concrete in the light of the New Canadian Standard. The effect of freezing fresh concrete at various ages is dealt with in some detail and tests results are given to illustrate the absolute minimum protection period and minimum protection methods.

Abstract:

Two series of lightweight concrete mixes made with expanded shale and slag aggregates were prepared for heat exposures between 300 C and 1000 C (572 F to 1832 F)/ To some concretes microfillers such as fly ash, silica flour, and calcined shale dust were added to replace 25 and 40% of the portland cement in the binder.

Abstract:

This paper reports the relationships of the strength of standard laboratory-cured cylinders to the strength of concrete in 24x24x66-inch (0.61 x 0.61 x 1.68-meter) columns and 24 x 24 x 8-inch (61 x 61 x 20-cm) slabs to that of cylinders cured under exposed winter conditions.
