Chemical Resistance of Concrete with Ceramic Waste
The ceramic waste aggregate concrete shows good resistance to the chemical attacks such as sulphate attack and chloride attack by preventing permeation of these chemicals. The compressive strength of the ceramic waste aggregate concrete is better and there is no considerable change in compressive strength before and after chemical attack.
Study of aggregate dormancy and its effects on the
Sep 10, 2018 · In our society today most of the aggregates that were used for concrete work were usually abandoned on site for some times with minimum of 6 month or more due to different factors as it may apply. Some which might be due to lack of fund by the client and tussles. This abandonment led to a situation where construction materials are piled onsite over a range of periods of time.
Recycled Concrete Aggregates: A Review SpringerLink
Mar 29, 2013 · After demolition of old roads and buildings, the removed concrete is often considered worthless and disposed of as demolition waste. By collecting the used concrete and breaking it up, recycled concrete aggregate (RCA) is created (Fig. 1).This paper focuses on coarse RCA which is the coarse aggregate from the original concrete that is created after the mortar is separated from the
tile aggregate in concrete production. Ceramic tiles were obtained from manufacturing industries, from construction and demolition sites, this cause''s environmental pollution. The utilization of crushed tile as a coarse aggregate in concrete would also have a positive effect on the economy. Therefore,
Walnut Shell for Partial Replacement of Fine Aggregate in
A central composite design (with 2*2=4 factorial points, 2*2 starpoints and 2 repetitions of central point) was adopted to optimize and model the effect of water/cement ratio (0.380.52), and walnut shells content (1.7258) wt.% for concrete mixes used walnut shell for partial replacement of fine aggregate.
Journal of Engineering Research and Studies EISSN 09767916 JERS/Vol.II/ Issue I/JanuaryMarch 2011/19 CONCRETE AND THE ROLE OF THE AGGREGATE Regarding concrete, which is the construction material of our era, the protection of the environment concerns three basic axes: • Use of high amounts of raw materials
The unit weight of the concrete ranged from 2365 to 2175 kg/m 3, depending on aggregate content (Figure 6) creasing the recycled aggregate content reduces the unit weight and density of the concrete, resulting in lighter concrete (Figure 6).The unit weights of the 15%, 20%, and 25% mixes were reduced by 8%, 11%, and 11.5%, respectively, compared to plain concrete.

Special Issue "New Trends in Recycled Aggregate Concrete"
Recycled concrete aggregates (RCAs) generated from construction and demolition activities have been recognized as a feasible alternative to natural aggregates (NAs). Naturally, the columns fabried with reinforced recycled concrete (RRC) have been proposed and investigated to promote the structural use of recycled aggregate concrete (RAC).

Properties of Concrete Containing Construction and
This paper reports the properties of concrete containing recycled coarse aggregate (RCA) sources from local construction and demolition (C&D) wastes and fly ash (FA) sourced from Western Australia (WA). The RCA is used as 25, 50, 75, and (by weight) replacement of natural coarse aggregate (NCA).

Effect of Recycled Coarse Aggregate on Concrete Properties
Abstract. This research was conducted with the use of recycled aggregate as modifiion. In terms of the use of recycled aggregate, the percentage of recycled aggregate should be determined because the strength of concrete would not be obtained by the high percentage of recycled aggregate.The scope of study is about comparison between recycle coarse aggregate and natural aggregate in terms of

aggregates, such as crushed limestone and gravel, while the demolition of old concrete structures offers significant sources of recycled concrete aggregate (RCA). Currently, RCA use in the United States is largely limited to nonstructural appliions, such as road base. Uncertainty and variability
crushed aggregate requires slightly higher values. Fine aggregate content is usually 35% to 45% by mass or volume of the total aggregate content. CHARACTERISTICS OF AGGREGATES. The important characteristics of aggregates for concrete are listed in Table 52 and most are discussed in the following section: Grading
