Determination of Radiative Heat Transfer Coefficient at High Temperatures Using a Combined Experimental-Computational Technique

Autor: Kočí Václav, Kočí Jan, Korecký Tomáš, Maděra Jiří, Černý Robert Č

Publikováno v: Measurement Science Review, Vol 15, Iss 2, Pp 85-91 (2015)

The radiative heat transfer coefficient at high temperatures is determined using a combination of experimental measurement and computational modeling. In the experimental part, cement mortar specimen is heated in a laboratory furnace to 600°C and th

Mechanical parameters of cementitious materials with superabsorbent polymer admixture

Autor: Fořt Jan, Maděra Jiří, Mildner Martin

Publikováno v: MATEC Web of Conferences, Vol 282, p 02063 (2019)

Concrete despite many performed studies still requires further research on material optimization towards its improvements. On this account the superabsorbent polymers can be viewed as very promising materials with a positive influence on various prop

Experimental determination of length changes of autoclaved aerated concrete during the freeze-thaw cycle

Autor: Sovják Radoslav, Maděra Jiří

Publikováno v: MATEC Web of Conferences, Vol 282, p 02074 (2019)

The aim of the paper is an experimental determination of the longitudinal expansion of autoclaved aerated concrete (AAC) during the freeze-thaw cycle. Longitudinal changes were measured with lasers and the surface temperature was measured using an in

Numerical simulation of degradation of porous building materials caused by freeze-thaw cycles

Autor: Maděra Jiří, Kruis Jaroslav

Publikováno v: MATEC Web of Conferences, Vol 282, p 02090 (2019)

Freeze-thaw cycles in porous building materials are studied in this contribution. Degradation and durability of many building materials as well as structural elements are tightly connected with the freeze-thaw cycles. The porosimetry curve and Gibbs-

Determination of effective specific heat capacity of interior plaster containing phase change materials

Autor: Kočí Václav, Maděra Jiří, Černý Robert

Publikováno v: MATEC Web of Conferences, Vol 282, p 02052 (2019)

A precise technique for determination of effective specific heat capacity of building materials is presented within this paper. The applicability of the technique is demonstrated on a PCM-enhanced plaster, being characterized by a phase change betwee

Monetized environmental assessment of interior thermal insulation

Autor: Fořt Jan, Maděra Jiří, Černý Robert

Publikováno v: MATEC Web of Conferences, Vol 282, p 02106 (2019)

Excessive production of carbon dioxide is viewed as one of the most threat to the current generation. While the industry and transportation sector significantly improve energy efficiency and more actions are awaited, the building sector still lacking
