In this paper, thermal insulating bonding mortar has been produced by the spent polystyrene foam particles, cement, sand, tackifier and water etc. It shows that thermal insulation performance and compressive strength of thermal insulating bonding mortar are similar with those of aerated concrete by comparison tests. In this paper, the new wall is made by thermal insulating bonding mortar and aerated concrete blocks, and the results show the thermal insulating performance of this wall can be improved and its cold bridge impact can be eliminated too. Correspondingly, the energy saving effect of buildings can be improved rapidly.

Insulating Properties

High moisture in building materials has a negative influence on their physical and thermal insulating properties. When building materials incorporated in a structure exceed the maximum permissible moisture, the material could change its properties to such an extent that its next usage is unfeasible. In case of thermal insulating materials, it causes serious degradation of thermal insulating properties. During the development of advanced thermal insulation plasters, long-term laboratory experiments were performed using masonry construction fragments, which focused on the study of their moisture proportions. For this purpose a new non-destructive method of electrical impedance was used, which enables measurements on defined levels in a matrix of test samples. Results obtained by measurements made on the surface of the samples were compared with the results obtained by a capacitive hygrometer. It was concluded that these methods provided similar results. The least moisture sensitive was the mixture, which was applied on masonry pillar E. In comparison with used thermal insulation plasters commonly used today this plaster shows considerably lower value of mass moisture under laboratory conditions, 1.38%. This pillar also exhibited the most uniform course of conductance measured along its height.

The foamed polypropylene (PP) with excellent thermal insulating property was prepared by using the nanosilica (SiO2) aerogels as nucleators, followed by mould pressing foam in cross-link. The weight ratio of SiO2/ PP, which was at the range of 0~ 2%, significantly affected the morphology and thermal insulating properties of the foamed PP. The results showed that the foamed PP can get excellent properties when the weight contents of SiO2aerogels was 1 %. The foamed PP with low density as 0.43 g/cm3and thermal conductivities at the range of 0.046~0.507 W.(m.K-1) was obtained by using this method.

This paper deals with the possibility of using pumice concrete as thermal insulation lining of industrial chimneys. Two formulas were prepared, the first from sulphate resistant cement and the second as a reference mixture from Cem I 42.5R. The thermal insulating properties of the prepared recipes will be evaluated as well as the resistance to the action of sulphates in 5 % sodium sulphate solution. No significant decrease in strength was observed when samples were stored in 5% sodium sulfate solution for 60 days. Only the reference series reported a significant unexpected decrease in strength.
