HENNEBERG-DE LEON, Andrea Mara  and  BRICENO, Daisy. Testing Stabilized Mud Mixtures for Filling and Plastering of Bahareque Walls. Ing. invest. y tecnol. [online]. 2016, vol.17, n.1, pp.143-154. ISSN 2594-0732.

The buildings of bahareque deteriorate mostly due to the vulnerability of the mud to moisture and the use of not adequate mixtures in its repairs. In order to improve the mud mixtures of the filling and mud cover of bahareque walls, was carried out a research whose results are presented in this article. This research studied the behavior of mud mixtures stabilized with cement and/or lime, to the effects of water. For this purpose a series of standardized tests were performed and it was designed a customized absorption test for the proposed stabilized mud mixtures. Mud mixtures with 10% of additives for the filling, and up to 15% of additives for the mud cover were proposed. In the mixtures was also added debris of clay or cement blocks to replace the stones that are usually used in the bahareque of the Zulia state, Venezuela. Due to the uniformity in the results of the mixtures with cement and lime additives, it is concluded that any of the proposed mixtures can be used in a rehabilitation of bahareque walls, but it is recommended the mud mixture with 10 percent of cement and clay blocks, because it had the lowest values of water absorption, that is to say, it is the most waterproof.
