“…However, this seems to be minimal in comparison with the effect of dilution, as shown by the results of LP40. Contrastingly, Mňahoncáková et al (28) found a positive effect on wet and dry cup tests performed on SCC mixes with 40% cement replaced with limestone. However, the w/cm of the mix was 0.28, and the total binder content was 632 kg/m 3 .…”

“…The clinker content per m 3 of concrete was therefore significantly higher than the clinker content in the studied LP40 mix. This means that LP in (28) was incorporated to increase the content of fines and to obtain a stable mix, rather than to replace part of the cement. It is therefore natural that the outcome is different in both cases.…”

“…Their results are based on the average of only two samples, which are not enough data to obtain reliable results for diffusion tests. Some studies on WVP of self-compacting concrete (SCC) (27)(28) have also been carried out, however the effect of water to cementitious materials ratio (w/cm) and the use of different SCMs on the WVP are not fully described.…”

Isothermal water vapour permeability of concrete with different supplementary cementitious materials

Water vapour permeability (WVP) is a key parameter for the sustainable thermal conditioning of buildings. The study of the WVP in concrete with supplementary cementitious materials (SCMs) allows for the design of structures with improved durability and sustainability. To our knowledge, there is insufficient experimental data in the literature regarding the WVP of concrete with SCMs.WVP tests were made on concrete mixes containing ground granulated blast-furnace slag (GGBFS) and limestone powder (LP) as a partial replacement for ordinary Portland cement, and of concrete mixes containing pozzolanic cement (NP). Results from three moisture gradients show that GGBFS induces the greatest reduction in WVP, followed by the NP. LP shows a diluting effect of the binder, which could be compensated by GGBFS in the ternary blend. From the comparison between the WVP and the capillary sorption rate, the influence of the SCMs on the connectivity of the smallest pores is assessed. RESUMEN: Permeabilidad de vapor agua isotérmica de hormigones con diferentes adiciones minerales.La permeabilidad al vapor de agua (PVA) es un parámetro fundamental para el acondicionamiento térmico sustentable de edificios. El estudio de PVA en hormigón con AM permite el diseño de estructuras con durabilidad y sustentabilidad mejoradas. A nuestro conocimiento, hay insuficiente información experimental en la literatura sobre PVA en hormigón con AM.Se hicieron ensayos de PVA en hormigones con escoria granulada de alto horno (EGAH) y polvo calizo (PC) en reemplazos parciales de cemento normal, y de hormigones con cemento puzolánico. Resultados de tres gradientes de humedad muestran que EGHA induce a la mayor reducción de PVA, seguida para por la puzolana natural. PC muestra un efecto de dilución del ligante, el cual pudo ser compensado por la EGHA en las mezclas ternarias. De la comparación entre PVA y velocidad de succión capilar, la influencia de las AM en la conectividad de los poros más pequeños es evaluada.

“…Fly ash (FA) is very often used as an admixture to SCC. It was experimentally proven that its addition reduces the spreading time [2], porosity [3], as well as shrinkage and creep [4]. The spherical shape of particles increases the flowability and workability of concrete.…”

“…The presence of fly ash slows down the reaction of alite and, consequently, the early strength of concrete is lower compared to usual values of SCC without mineral admixtures. Due to reduced porosity, concretes containing fly ash generally achieve higher final strengths [3], but this effect greatly depends on the quantity of ash added. Excessive FA content in concrete can lead to decrease in strength [5][6][7][8].…”

Although the use of waste materials as mineral admixtures for self-compacting concrete can contribute to solving the problem of their disposal, the effect of such use should be further explored. The influence of fly ash, powdered waste brick elementsroof tiles, flotation tailing and silica fume, on the consistency, compressive strength, bending tensile strength, and tensile splitting strength of concrete, is studied. Selfcompacting concrete mixtures test results are compared to a common concrete mixture.
