Utilization of Eaf Metallurgical Slag in “green” Belite Cement
În acest studiu, zgură de cuptor cu arc electric (EAFS) colectată de la Sovel S.A., Grecia şi calcar şi argilă, de la compania de ciment Titan S.A., Grecia, au fost utilizate pentru producerea şi caracterizarea cimenturilor tip belitice. Trei tipuri de clincher au fost preparate: belitic fara adaos de zgură folosit ca referinţă (BC), unul cu 5wt% EAFS (BC5) şi un altul cu 10wt% EAFS (BC10). Ana...
متن کاملA study on strength and durability of self-compacting concretes made of recycled aggregates
Given the development of construction industry and design and implementation of high rise buildings with complex sections and various geometrical forms, the use of self-compacting concretes has received the attention of construction engineers and provided great advantages. Due to the increasing air pollution in cities, governments encounter the important issue of repelling the pollutants in whi...
متن کاملDynamic Fracture Behavior of Steel Fiber Reinforced Self-Compacting Concretes (SFRSCCs)
Three-point bending tests on notched beams of three types of steel fiber-reinforced self-compacting concrete (SFRSCC) have been performed by using both a servo-hydraulic machine and a drop-weight impact instrument. The lo ading rates had a range of six orders of magnitude from 2.20 × 10-3 mm/s (quasi-static) to 2.66 × 10³ mm/s. These SFRSCCs had the same matrix, but various types of steel fiber...
متن کاملDurability of Self-compacting Lightweight Aggregate Concretes (LWSCC) as Repair Overlays
For rehabilitation of damaged concrete structures, the durability of repair overlay is a very important issue. Self-compacting concretes (SCC) are known as a suitable repair overlay materials. In this study, the durability of different self-compacting lightweight aggregate concretes (LWSCC) and effect of lightweight aggregate type on them is investigated. 3 mix designs of LWSCC containing three...
متن کاملA Comparison of the Microstructure of self compacting concretes containing nano and microsilica
Abstract Self compacting concrete (SCC) is a new construction material in the world. The aim of this research is to construct self compacting concrete with high compressive strength using combination of nano silica and micro silica. For this purpose, nano silica, micro silica, Portland cement type 2, superplasticizer (SP), and gravel and sand have been used. Three different groups of samples wi...
