Particles spasing of supplementary cementitious materials in binary blended cements
Języki publikacji
Abstrakty
Zbadano wpływ dodatku wapiennego [DW], dolomitowego [DD], metaillitu [MI] i prażonej gliny illitowej [GP] na gęstość mikrostruktury zaczynów z cementów dwuskładnikowych, pod względem grubości warstwy wody [GWW] i optymalnego zapotrzebowania na wodę [OZW]. Przeanalizowano wpływ tych uzupełniających materiałów cementowych [UMC] na rozpływ zaczynów i zapraw cementowych oraz omówiono wytrzymałość zapraw na ściskanie. Wyniki wykazują, że wpływ dodatków UMC na gęstość mikrostruktury zaczynów jest ściśle związany z rozkładem wielkości ziaren. Optymalna zawartość UMC zapewnia wieloskładnikowym cementom maksymalną gęstość mikrostruktury zaczynów. Wpływ na rozpływ zaczynów zależy nie tylko od gęstości mikrostruktury, ale także od powierzchni ziaren, a zastosowanie wymienionych UMC zwiększa wytrzymałość zapraw na ściskanie.
The effect of limestone filler [LF], dolomite filler [DF], metakaolin [MK], and metaillite [MI] additives on the packing density of the binary blended cements were studied using of the water film thickness [WFT] and the optimal water demand [OWD]. The influence of these supplementary cementitious materials [SCM] on the flowability of cement pastes and mortars was analyzed and the compressive strength of mortars was discussed. The results indicate that the incorporation of these SCM on the packing density is highly related to the particle size distribution and the optimal addition of SCM to the blended cements, assures maximum packing density. The effects on flowability not only depend on packing density but of the surface area of particles and the addition of SCM enhance the compressive strength of the mortars.
