Effect of natural zeolite on the properties of high performance concrete
Języki publikacji
Abstrakty
Zbadano szereg właściwości fizycznych betonu wysokiej wartościowości, w którym zastępowano cement portlandzki naturalnym zeolitem w ilości aż do 40% masowych. Uzyskane wyniki doświadczalne wykazują, że zastąpienie 10% cementu zeolitem stanowi korzystne rozwiązanie. Ta zawartość zeolitu zapewnia dobre właściwości betonu, między innymi transport wody i pary wodnej utrzymuje się na korzystnym poziomie oraz parametry cieplne są akceptowalne, a także wytrzymałość spełnia wymagania BWW. Natomiast beton zawierający 10% zeolitu nie ma odporności na zamrażanie w obecności soli odladzających. Z tego względu beton, nawet z tym małym dodatkiem zeolitu, nie powinien być stosowany w konstrukcjach narażonych na takie zagrożenia.
Bulk density, matrix density, open porosity, pore size distribution, compressive strength, resistance against de-icing salts, water absorption coefficient, water vapor diffusion resistance factor, adsorption and desorption isotherms, thermal conductivity, and specific heat capacity of high performance concrete containing up to 40% of natural zeolite as Portland cement replacement were measured and compared with reference Portland cement concrete. Experimental results show that the replacement of Portland cement by natural zeolite in the amount of 10% by mass can be considered the most suitable option among the studied mixes. At this replacement level, the increase in open porosity, thus in liquid water transport properties is within reasonable limits, the mix retains its high performance character as for the compressive strength, the water vapor transport parameters, and thermal parameters are acceptable. The poor resistance against de-icing salts presents, however, a limitation even for the mix with the 10% zeolite dosage. Therefore, the mixes analyzed in this paper should not be used in such cases where de-icing salts are likely to act during their service life.
