Steam Cured Self-Consolidating Concrete and the Effects of Limestone Filler
… associated with replacing 15% of the cement by limestone filler on the mechanical properties and durability performance of self-consolidating concrete designed and cured for precast/prestressed applications. This study investigates the role of limestone filler on the hydration kinetics, …

Chloride transport and chloride thresholdvalues-Studies on concretes and mortars with Portland cement and limestone blended cement
… such as blast-furnace slag, fly ash and limestone filler. This is done by the cement and concrete industry to reduce the CO2 emissions linked to Portland cement manufacturing, by limiting the use of clinker in the cement. The main objective of this work has been to further clarify the …

Role of cement content in determining resistance of concrete to reinforcement corrosion
… were improved, particularly with the inclusion limestone filler (with cement reduction)to maintain the mix fines content.Stage 2 indicated that observations noted for permeation properties were not influenced by aggregate or cement type. However, for a given mix, the resistance of concrete to …

Design of dense graded cold bituminous emulsion mixtures and evaluation of their engineering properties
… types of dense bituminous mixtures containing limestone aggregate, river sand and limestone filler, blended in appropriate proportions. The study presents information regarding the properties of two dense graded bituminous mixtures i. e. a gap graded "Cold Rolled Asphalt" (C. R. A. ) and a …

Development of a New Cold Binder Course Emulsion Asphalt
… material, alkali activated binary blended cement filler (ABBCF), made from Paper Making Sludge Ash (PMSA) and a Fluid Catalytic Cracking Catalysts Residue (FC3R) activated by a waste NaOH solution (W-NaOH). Incorporation of the PMSA and FC3R was achieved through the replacement of conventional …

Alkali-Aggregate reaction in Western Cape concrete
… were replicated with the exception that an inert limestone filler, “Kulubrite 10”, was used instead of the reactive cement extenders. It was observed that the limestone filler does reduce the expansion but to a much lesser extent than the reactive cement extenders. This implied that the cement …

Development of a simulated natural carbonation test and durability of selected CEM II concretes
… aggregate types, Thames Valley gravel, crushed limestone and crushedgranite were also tested and were shown to have a minimal effect on the carbonation resistance ofconcrete. The influence off ines (particles <125gm, including cement) on carbonation resistance wasalso studied. Adjusting the …

Development of a New Environmentally Friendly Glass Fibre Reinforced Cold Mix Microasphalt with High Resistance to Cracking and Deformation.
… bitumen emulsion, primary & secondary filler, and iii) mechanical testing of control microasphalt, glass fibre reinforced cold mix microasphalt and green cement filler microasphalt. Chemical testing involved a regime to show the affinity between aggregates and bitumen emulsion in the …

Development of a New High Performance Cold Mix Asphalt
… curing time of CBEMs by replacing conventional limestone filler (LF) with a new secondary cementitious filler made primarily from waste materials. Ultrasound technology was used to reduce the size of the bitumen droplets through the cavitation phenomenon. A cationic bitumen emulsion (C50B4) was …
