The Use of Aluminum Waste for Concrete Production

Abstract

Aluminum wastes (AW) have been used to produce concrete samples used for this work. Tests on the setting times, compressive and flexural strengths were conducted at replacement levels of 5, 10, 20, 30 and 40 % by weight of cement. The results showed that AW can be used as a retarder and thus, a good material for hot weather concreting. Optimum replacement values for the compressive and flexural strengths are at 10 % replacement ant the statistical models developed on them are significant.

Effect of Incorporation of Cellulose Industrial Residue in Concrete Matrix

“…This process of strength development is expected to continue with hydration period until completion of hydration of cement -Cellulose industrial residue mixture [3]. These results confirm those obtained by other researchers using similar materials [9,20,21]. …”

“…Thus, cellulose industrial residue defers the hydration of the paste and extends the setting time. This shows that cellulose industrial residue can be used as a retarder and thus, is a good material for hot weather concreting, like aluminum waste [20]. Table 4 shows the compressive strength of OPC/CIR concrete mixes with different CIR contents and with different hydration period.…”

Pengaruh Penambahan Serpihan Aluminium Sebagai Bahan Parsial Semen Terhadap Kuat Tekan dan Kuat Tarik Belah Beton

“…Kuat tarik belah beton adalah nilai kuat tarik tidak langsung dari benda uji beton yang berbentuk silinder, yang diperoleh dari pembebanan benda uji tersebut yang diletakkan secara mendatar, sejajar dengan permukaan meja penekan mesin uji tekan [5] . Kuat tarik belah diperoleh dengan metode pengujian kuat tarik belah menggunakan universal testing machine (UTM).…”

Feasible Use of Recycled Concrete Aggregates with Alumina Waste in Road Construction

“…AW has also been used as a cement replacement in the manufacturing of conventional concrete. Elinwa [ 31 ] reported that with a 10% cement replacement, the compressive and flexural strength was similar to that of conventional control concrete.…”
