Natural Aggregate Replacement - an overview ...
9.2.1 Glass as natural sand replacement. Green, amber, flint, blue, and mixed colors of glass with different particle size distribution, covering both coarse and fine aggregates in concrete mixes have been used. With regard to the proposed specification for recycled glass as natural aggregate replacement in concrete, such limits refer to AARB (2010), Byars, Zhu and …
Aggregate Replacement - an overview | …
The EPS aggregate replacements with natural aggregate ranged from 0% to 95%. They concluded that the permeability of EPS concrete with higher strength and density (e.g., 1500 kg/m 3) is similar to that of NWC. The water absorption at 30 min was between 2.2% and 11.5% and total water absorption was between 6.7% and 28.8%. In
Natural Aggregate - an overview | ScienceDirect …
The slag proportion of replacement of natural aggregates is an important factor affecting successful use. The optimum proportion should be decided based on laboratory tests on selected proportioned mixed for a specific slag. In general, steel slag used in paving mixes should be limited to replacement of either the fine or coarse aggregate fraction, but not both, because …
replacing of natural with artificial fine aggregate
1 Replacement of natural fine aggregate by 60 artificial fine aggregate is the best result because of maximum strength and minimum area of crack 2 When the replacement percentage of artificial sand is increases more than 60 the compressive strength decreases and area of crack increases replacing of natural with artificial fine aggregate

replacement of natural aggregate with recycled aggregate were in close proximity while 100% replacement has a very low split tensile strength with a slightly decrease of …
Integrated assessment of the use of recycled …
The use of recycled concrete aggregate (RCA) replacing natural aggregate (NA) to produce concrete named as recycled aggregate concrete (RAC) has gained increased importance in the last few decades. Despite many visible advantages associated with the initiative, RAC is not manufactured at commercial scale to replace natural aggregate concrete (NAC) used as …
Replacement of recycled coarse aggregates with natural ...
In this study we replaced natural aggregates with recycled aggregates in concrete cubes. This is the first part of the study we have to do. Here we are trying to see a pattern of how the strength decrease once we replace natural coarse aggregate (NCA) with recycled coarse aggregates (RCA). The percentages of replacement will be 0%, 50% and 100%. The test and design is as …

REPLACEMENT OF FINE AGGREGATE WITH JAROFIX IN CONCRETE
namely Jarofix, is used in effectively replacing fine aggregate in concrete. The properties of concrete such as water absorption, workability, mass and density, compressive strength, split tensile strength and flexural strength were studied with 10%, 20%, 30%, 40% and 50% of Jarofix replacing fine aggregate. As the percentage of jarofix added to

Replacement of Natural Fine Aggregate by …
This stone presents the applications of replacement of natural fine aggregate using copper slag. The study is conducted by replacing the fine aggregate from 0 to 100% at the interval of 20% on M25 grade concrete and 1.8% superplasticizer by weight of cement. The compressive strength, split tensile strength and flexural test is studied and reported. It is observed that replacement of natural ...
