“…This is because feldspar contains alkaline oxides i.e., K 2 O and Na 2 O, which melt at relatively low temperature, and acts as fluxing agent and assist in liquid phase formation [1,4,5,27]. Based on this facts, the tiles made with compositions with high percentage of feldspar i.e., composition C2, C3, C4 and C5 had the lowest water absorption.…”

“…This is because the bulk density of the porcelain body decreases with the decrease in feldspar content and vise versa. The fluxing oxides help in the formation of liquid phases which fill the pores and increase the bulk density of the porcelain body [27]. The bulk density of the porcelain body reaches its maximum when there are enough liquid phases to block the open porosity.…”

“…This may be attributed to low percentage of kaolin which was responsible for the formation of unstable aluminosilicate spinel phase. It is the unstable aluminosilicate spinel phase which forms mullite phase and mullite forms the liquid phase [27][28][29][30]. The liquid phase is responsible for blocking the open porosity, increase the density and decrease water absorption.…”

“…4. Generally the water absorption decreases with increase in firing temperature due to the formation of the liquid phase and densification at high firing temperatures [26,27]. The liquid phase formed is the one which fills the pores and decreases the porosity.…”

“…Although the standard requires water absorption of the porcelain tiles to be less than 0.5%, this is only necessary for floor tiles [27]. According to technical standards the tiles with water absorption higher than 10% can be used as wall tiles [17].…”

Kaolin and quartz from Pugu; and feldspar from Morogoro were investigated to determine their suitability as raw materials for the production of porcelain tiles. From the mineralogical analysis, kaolin sample was found to contain kaolinite (Al 2 Si 2 O 5 (OH) 4 ) and quartz (SiO 2 ); quartz sample was found to contain only quartz mineral silica (SiO 2 ); and feldspar sample was found to contain albite (NaAlSi 3 O 8 ) and microcline (KAlSi 3 O 8 ). The major chemical compounds found in kaolin and feldspar were SiO 2 and Al 2 O 3 , and quartz sample was found to contain SiO 2 and SO 3 . The tiles made from the raw materials and fired between 900 °C and 1200 °C were found to have the water absorption of 12.4 -13.7%, bulk density of 1.89-1.95 g/cm 3 , apparent porosity of 24.1-26.0%, linear shrinkage of 0.0-1.7%, compressive strength of 107.4-380.4 kg/cm 2 and loss on ignition of 3.6-6.0%. Among the studied compositions and firing temperatures, tiles made from a blend containing 40% kaolin, 45% feldspar and 15% quartz; and fired at 1100 °C were found to have the best properties for the production of porcelain tiles. This is an indication that the Tanzanian kaolin, quartz and feldspar are suitable raw materials for the production of porcelain tiles.

Around 21.7 million tons of urban solid waste are produced in North Africa and the Middle East. The amount of glass waste produced is 0.87 million tons. The amount of urban glass waste (UGW) produced in Egypt was 2280.8 tons per day. This paper aims to study the effect of partial replacement of UGW in the production of ceramic floor tiles to save the production cost and raw materials. The characteristics of the basic raw mixture of floor tiles and UGW were studied. The waste was collected, crushed and ground to be blended with the basic mixture in different percentages that ranged from 0 to 35%. The specimens were molded under uniaxial pressure followed by drying and firing at temperatures ranging from 1050 to 1120 °C. The characteristics of the fired specimens have been determined and compared with the International Standard Limits. The results showed that specimens containing waste ranging from 25% to 35%, fired at 1100 °C with a soaking time of 15 min have a modulus of rupture of 18.9 to 19.7 MPa, breaking strength of 600 to 613N and water absorption of 9.78% to 8.2% respectively that fulfilled the lowest requirements for the ISO 13006 for dry pressed tiles Group BIIb.
