A portland cement (PC) with a mineralogical composition (Bogue) of C 3 S=58%, C 2 S=18%, C 3 A=2% and C 4 AF=13% was used as reference in all mortars. Its low C 3 A content is characteristic in portland clinkers produced in Argentine. Supplementary materials used were limestone filler (LF) obtained from a good …
Adding limestone filler to metakaolin-cement mixtures improved their workability as its water demand was lower (Table 1) and the needed superplasticizer content was lower ( Table 2).
Limestone filler contains 85% of CaCO 3 in calcite form without clay minerals. The main impurity was quartz (SiO 2 =11%) and it was ground at a Blaine fineness of 710 m 2 /kg and the parameters of particle size distribution curve were n=0.61 and x′=13.2 μm. The limestone-blended cement was obtained by replacing 20% of …

The main objective of this research is to clarify the mechanical behavior and ability to use Portland limestone cement in producing self compacted concrete, due to the beneficious effec of the ...
Self-Compacting concrete is a type of concrete that gets compacted under its self-weight. It's commonly abbreviated as SCC and defined as the concrete which can placed and compacted into every corner of a formwork; purely means of it's self-weight by eliminating the need of either external energy input from vibrators or any type of compacting effort. …
Limestone filler is considered to be a material of higher stiffness compared to concrete, which leads to a higher modulus of elasticity. Elyamani et al., 2014, compared the effect of different fillers on the rheological and mechanical properties of SCC. The non-pozzolanic fillers, such as marble dust, alleviated the phenomena of bleeding and ...
Fill in potholes in your driveway. Fill in any potholes holes on the driveway with gravel fillings to prevent water from collecting when it rains. If water collects on the driveway, it moves under and separates it from the sub-base, making it less stable over time. Filling potholes also ensures vehicles remain stable while passing on the driveway.
Limestone filler was used in this study as the reference material. The following tests were performed: grading (air jet sieving), quality of fines according to methylene blue test, water content ...
