Concrete moisture penetration

Moisture is transferred from the outside of the building to the basement interior by four mechanisms: There are just three sources of moisture: Isteita, The effect of thermal conduction on chloride penetration in concrete [M. Figure 7 presents the values of D HT for three different temperature gradients. Durability related transport properties of OPC and slag cement mortars hardened under different environmental conditions. Influence of environment on durability of fly ash cement mortars. The concrete samples were kept in nonsaturated and isothermal condition.

Preventing Moisture Penetration in Architectural Masonry Walls

Pore pressure in heated concrete walls: The model is validated by comparing the numerical results against the available experimental data and a good agreement is observed. Simultaneous moisture and heat transfer in porous systems with particular reference to drying. Parapets often bear the force o The same trend was observed in previous studies [ 22 , 23 ]. As seen from these figures, at any fixed depth, pore relative humidity of nonsaturated concrete is lower than the saturated condition.

Some building wall materials such as gypsum board and polystyrene board, will be penetrated out easily by indoor water vapor in a daily moisture variation period. In addition, the high level of internal moisture can help to accelerate the chloride penetration in concrete and trigger corrosion of embedded steel bars, especially in marine structures [ 13 , 14 , 15 , 16 , 17 , 18 , 19 ]. Journal List Materials Basel v. University of Illinois at Urbana-Champaign , However, it is based on an assumption that the material is thicker than the TMPD. For this reason, sumps should have an airtight cover. The total amount of moisture contained in concrete, the so-called moisture content, is generally represented by water content or by pore relative humidity.

There are very few reference documents which provide information on the moisture content data which could be used as a guide or point of reference by surveyors or maintenance managers in the field. Simultaneous moisture and heat transfer in porous systems with particular reference to drying. Undertaking surface moisture content readings is sufficient for the competent surveyor or architect to assess any impacting moisture issue and propose appropriate, remedial actions. However, Roels and Janssen 19 found that the influence of the surface film resistance for common building materials is hard to be neglected. Moisture buffering capacity of heavy timber structures directly exposed to an indoor climate: The frequency characteristics of the vapor flux between the material and ambient air can be calculated by transfer function TF model 41 analytical model , as described in equation Following, some application analysis is presented using the calculated TMPD.
