Abstract


In a thorough previous research (1), it appeared that creation, evolution and development of the values of compressive mechanical strength (CS) and flexural strength (FS), measured in specimens 1x1x6cm of mortar type ASTM C 452-68 (2), manufactured by ordinary Portland cement P-1 (14.11% C3A) or PY-6 (0.00% C3A), metakaolin and gypsum (CaSO4∙2H2O) -or ternary cements, CT-, were similar to the ones commonly developed in mortars and concretes of OPC. This paper sets up the experimental results obtained from non-traditional mortars and concretes prepared with such ternary cements -TC-, being the portland cement/metakaolin mass ratio, as follows: 80/20, 70/30 and 60/40. Finally, the behaviour of these cements against gypsum attack, has been also determined, using the following parameters: increase in length (ΔL%), compressive, CS, and flexural, FS, strengths, and ultrasound energy, UE. Experimental results obtained from these non-traditional mortars and concretes, show an increase in length (ΔL), in CS and FS, and in UE values, when there is addition of metakaolin.
