cold crushing test of refractory brick

Standard test methods do not necessarily give the most useful data. The cold crushing strength of a fired brick is generally much greater than its crushing strength at higher temperatures; rectangular blocks heated from one end do not expand as expected from the free thermal expansion; nor is the Young's modulus of a stressed block the same as

    Cold Crushing Strength (CCS) of Refractory Bricks Cold crushing strength (CCS) of a refractory brick represents its strength. That is it tells us how much load that refractory can bear in cold conditions

  • cold crushingstrength and high wanhaorefractory

    Cold crushing strength is the ultimate load per unit area of dense shaped refractory products can withstand without damage at room temperature. The cold crushing strength of pressure-resistant refractory products has a great impact for the production, transportation and use performance, so higher cold crushing strength is better. The high crushing strength indicates that the processed quality is …

  • abrasion, testingrefractoriesfor resistance

    As a further note, abrasion resistance tends to track with the cold crushing strength of refractory, and 70% alumina brick has CCS values of about 6,000 psi to about 7,500 psi. Not all brick refractories in the same alumina class will have equal abrasion resistance

  • comparison of hot andcoldmodulus of rupture for silicabrick

    The report shows a comparison of cold crushing, cold modulus of rupture and hot modulus of rupture on a series of silica brick made from special mixes, commercially burned. Conclusions.—The modulus of rupture of a silica brick at 1350°C is approximately one‐third the strength at atmospheric temperature. For this series it averaged from 130 to 189 lbs. per square inch

  • refractoriness under load restar

    The temperature range in which the softening of refractory products occurs is not identical with the melting range of the pure raw material; therefore it must be reliably determined. Refractoriness under load (RUL) is a measure of the deformation behaviour of refractory ceramic products subjected to a constant load and increasing temperature

    Pores in Refractory Bricks (Porosity) Porosity is the percentage relationship between the volume of the pore space and the total volume of the refractory sample. Apparent Porosity does not include the volume of the sealed pores. The True Porosity includes the volume of the sealed pores also. The usual difference between the apparent porosity and the true porosity is of the order of 1 to 2 percent unless the …
