The paper presents an analysis of the possibilities of using glass waste from recycled lighting materials as aggregates for cement concrete. The research material was obtained from a company that utilizes electrical waste. Glass from pre-sorted elements was transported to the laboratory and crushed in a drum crusher. In this way, the aggregate obtained was subjected to the basic tests that are ...

The properties of hardened original fly ash (OF) or ground fly ash (GF) at a ratio of 30:70 by weight concrete were evaluated with respect to the relative water absorption and was used as a binder to cast concrete without Portland cement. The of aggregates combining the quality and volume of RA.

Feb 01, 2002· Three concrete mixes, as shown in Table 4, were prepared.Since there is no existing standard method of designing concrete mixes incorporating RA, the method of mix design proposed by the Cement and Concrete Institute (C&CI) was employed to design a concrete mix containing natural coarse aggregate. The mix was designed to have a 28-day target compressive strength of 30 …

Sep 23, 2019· After decades of studies, the partial use of coarse recycled aggregates is considered acceptable, yet the use of fine recycled aggregates (FRAs) is highly restricted in concrete production. This restriction is based on technical concerns; for example, the presence of FRAs in concrete allegedly hinders its performance beyond acceptance.

This experimental study investigates the effects of the aggregate surface conditions on the compressive strength of quick-converting track concrete (QTC). The compressive strength of QTC and interfacial fracture toughness (IFT) were investigated by changing the amount of fine abrasion dust particles (FADPs) on the aggregate surface from 0.00 to 0.15 wt% and the aggregate water …

These results are not surprising because concrete containing recycled aggregates has up to 50% more paste volume, and creep of concrete is proportiona l to the content of paste or mortar in concrete [Lamond et al. 2001]. 2.5.2.7 Permeability Concrete m ade from recycled aggregates W/C of 0.5 to 0.7, has permeability two to five times that of ...
