“…4), since now the CELU+PEM mixture shows a behavior slightly above the control at the ages 7 and 14 days and then decreases a little at the age of 28 days, reach again the strength of the control mixture in the last age. The better performance of the CELU+PEM mixture can be attributed to the particle size of one of the two components, in particular to the PEM, since a previous research reported an increase in physical solicitation using substitutions of PE with particle size less than 44μm [15]. The test results of UPV and electrical resistivity, in which it can be seen as the mixture CELU+PEM presents a significant increase at the age of 28 and 14 days respectively, spreading the control both the CELU mixture are presented in Figs.…”

This work shows the results carried out by mixtures of Portland cement mortars with twoadditions: ash brick ovens (CELU) which acting as pozzolan, and ground expanded perlite (PEM)as filler. The objective of this research is to determine whether by adding a pozzolan and fillermixtures base Portland cement is possible to increase physical and mechanical behavior. There were3 mixtures: the control and 2 more: one with substitution of 7% CELU, and other with 7% CELU+5%PEM respectively, carrying out tests of normal consistency, setting, fluency, simple compression,indirect tension, ultrasonic pulse velocity and electrical resistivity at the ages of 3, 7, 14, 28 and 120days. The results were favorable in the mixture that incorporates both materials (CELU+PEM).

“…Clays (most well-known is metakaolin) are an effective replacement material after calcination for blended cement production [9,10]. Moreover, there are also studies on the use of binary or ternary blended cements such as metakaolin-limestone [11][12][13], fly ash-limestone [14][15][16][17]. The results of studies conducted on calcined clay blended cements and binary or ternary blended cements that contains synergic reactions are quite pleasing.…”

Natural marl which is calcined at appropriate temperature has potential being alternative pozzolan. Therefore, the calcined marl is wanted to be used as replacement material in blended cements with less clinker. This situation leads to improved performance of cement/concrete, reduced CO2 emissions, saving of energy. The properties of used pozzolan positively effect to some behavior of concrete. Shrinkage is one of these properties. The shrinkage of concrete is inherent property that needs to be control. Moreover, the shrinkage of concrete becomes even more important in some applications such as mass concrete, prestressed concrete. The aim of study is to determinate how will affected shrinkage of concrete containing alternative pozzolan calcined marl blended cements. Accordingly, the natural marl was calcined at 800 °C for pozzolanic activation. The calcined marl was replaced with Portland cement at ratios of 0, 10, 30, 50 wt.%. The setting times, volume expansion, water demand, density, performance energy evaluation of blended cements were determined. The autogenous-drying shrinkage, mass loss and compressive strength tests were performed on concretes containing calcined marl blended cements. According to the results, pozzolanic activity of calcined marl and properties of blended cements containing calcined marl are comply with limit values of TS 25 and EN197-1. It was observed that autogenous-drying shrinkage and mass loss of concretes containing calcined marl blended cement were lower than that of concretes containing Portland cement. On the other hand, it was seen that compressive strength of concretes was increased up to 50 % replacement ratio.
