A by-product of the manufacturing process when steel and iron are melted down ground granulated blast furnace slag The advantages of slag cement are improved workability and pumpability in the plastic (unhardened) concrete In the hardened concrete the use of slag cement increases 28 day strengths reduces permeability and heat of hydration increases sulphate resistance and controls the alkali silica reaction The use of slag cement during hot weather is especially useful because set times in the

Natural Sand In Concrete By Quarr

Aggregates for Concrete bination of gravels or crushed stone with particles Natural gravel and sand are usually dug or dredged from a pit river lake or seabed Crushed stone is produced by crushing quarry rock boulders cobbles or largesize gravel Crushed aircooled blastfurnace slag is also used as fine or coarse aggregate

The Effect of Aggregate Properties on Concrete Aggregate is classified as two different types coarse and fine Coarse aggregate is usually greater than 475 mm retained on a No 4 sieve while fine aggregate is less than 475 mm passing the No 4 sieve The compressive aggregate strength is an important factor in the selection of aggregate Aggregates for Concrete Civil Engineering aggregates

supplementary cement replacement materials in concrete The combined effect of copper slag and fly ash as a partial replacement of cement on flexural strength of concrete has been investigated Fifteen mixes were prepared at different replacement levels of copper slag (0 to 20% increment of 5%) and fly ash (0 to 10% increment of 5%) with cement Three prisms (150 mm X 150 mm X 700 mm) were

The effect of these materials and their mix proportions on the properties were examined Based on the results the fresh properties of UFC were much improved and hardened performances were also improved by using OPC at normal temperature Keywords Ultra-hight-strenght fiber-reinforced concrete Blast furnace slag Fineness and Workability 1

For details on upcoming Concrete Institute of Australia events the effect of an optimised overall aggregate grading on pumpability and the benefits of minute bubbles of air on workability will all be explained in detail - along with many other key aspects The seminar will have a strong focus on technology and will aim to provide the audience with an opportunity to go back to basics in

Chapter 5 Aggregates for Concrete alkali content of the cement used in the old concrete has little effect on expansion due to alkali-silica-reaction For highly reactive aggregates made from recycled concrete special measures discussed under "Alkali-Silica Reaction" should be used to control ASR Also even if expansive ASR did not develop in the original concrete it can not be assumed

Typically fly ash replaces cement at 15% to 25% by weight and slag replaces cement at 15% to 40% by weight with little effect on concrete mix design placement curing and finishing Using fly ash and slag at these proportions provide minimal cost impact improved workability finishability and pumpability no change in plastic shrinkage or abrasion resistance and less bleeding

1 Introduction

This study aims to estimate the pumpability and shootability of wet-mix shotcrete (WMS) made with crushed aggregates and various admixtures such as silica fume fly ash ground granulated blast furnace slag (GGBFS) metakaolin and steel fiber based on rheological properties The IBB rheometer was employed as an apparatus to measure the rheological properties of freshly mixed shotcrete such as

In the grout mix fly ash and slag are often substituted for a portion of the cement for 24% to 30% to produce mixes with higher workability and pumpability reduced bleeding and reduced shrinkage Grout is so fluid that the workability is typically measured using a flow cone For concrete a pea-gravel size aggregate with around 42% sand

Various mix proportions of concrete were prepared and the effect of unsuitable concrete works exceeded impact due to free fall from the height of 4 0m without shooter and exceeded horizontal move using internal concrete vibrator was discussed As a result it was confirmed that air-void diameter and air content in hardened concrete was influenced by concrete works and mix proportions Total

The MiniShot spraying device used allows for the lab-scale spraying of 'micro-concrete' or 'fines-based concrete' that is to prove the pumpability and sprayability of the concrete mix at the corresponding scale The mixing sequence was as follows (1) The binder components (cement GBFS and FLS) and in most cases the Nekafill aggregates were mixed with the water in the Hobart

fly ash (FA) granulated blast-furnace slag (BFS) and silica fume (SF) are widely used in self-consolidating concrete (SCC) due to their several advantages First of all the high amount of paste requirement for better flow of SCC is easily achieved by SCM which is superior to using only portland cement (PC) Also utiliza-tion of these SCM in SCC reduces the demand for PC fine fillers
