Abstract

Effect of pine resin on the thermal and mechanical properties of plaster with pumice

“…Samples with high pumice content (60% and 80%) had lower thermal conductivity than various plaster materials (Table 5), mainly due to the porous nature of the pumice and the resin added to the plaster. The samples had the same thermal conductivity values as those in Ref [5] and lower thermal conductivity values than those in Ref [2,4,15,20,21] (Table 6). The aggregate ratio and resin addition gave the plaster samples sound and thermal insulation.…”

“…Bicer [4] mixed fly ash aggregate and gypsum (a binder agent) at ratios of up to 90% to produce plaster with thermal conductivity of 0.248 W/mK. Devecioglu and Bicer [5] added 80% EC and 1% tragacanth resin to produce concretes with thermal conductivity of 0.140 W/mK. Many other researchers have conducted similar studies on EC aggregate concretes [6][7][8][9][10][11][12][13].…”

Effect of production temperature on thermal and mechanical properties of polystyrene–fly ash composites

“…Table 4 shows that compressive strength values (samples [16][17][18] are greater than those obtained by Babu et al, 26 Li et al 19 (density: 1.150 g/cm 3 ), Kaya and Kar 33 (EPS (80%) þ cement (20%)), Khedari et al, 41 and Devecioglu and Bicer. 43 In the abrasion test performed on the samples, as PP ratio increased, abrasion ratio decreased from 1.90% to 0.5% with a ratio of 73.68% ( Figure 5). Figure 6 shows that as the production temperature increased (275 C), water absorption ratio decreased.…”

Gözenekli Agregalı Betonların Isıl ve Mekanik Özellikleri

“…Not every clay that can be found in nature expands. Early sintering clay, sand clay and clay schist are the raw materials used for producing growing clays [17][18][19][20][21][22][23]. Expanded clays are immediately processed in rotary furnaces heated to over 1000 C at high temperatures.…”

“…Xue et al [14], Gnip et al [15], Demirboga and Kan [16] can be cited as examples of studies on the reuse of waste EPS for thermal recycling in a modified form and its physical properties. Devecioglu and Bicer [17], Bouvard et al [18] and Chen and Liu [19] studied on thermal and mechanical properties of concrete with expanded clay aggregate Bartolini et al [20] mixed the expanded clays and epoxy resin which was used as a binder. Rossignolo et al [21] studied production of sturdy prefabricated constructional components by means of using the expanded clay aggregates, Vasina et al [22] mixed expanded clays of various diameters with cement, fuel ash and plasticizer additive, while also carrying out a research on the acoustics performance of the samples.…”
