In many war torn and poverty stricken regions, the indigenous architecture has been heavy mud and wattle roofs on thick mud walls. These structures, while cool in the summer, are of very low strength, are maintenance intensive, are time consuming to build, and are largely in massive disrepair. Replacing these mud structures with the light weight roofs of latex concrete produces a permanent architecture significantly more safe and strong, of very low maintenance, and of remarkably low cost, as the roofs can be built by available unskilled labor. The time required for reconstruction is considerably shorter than the time required to replace the older heavy construction, and the self-help characteristic of this new form of construction leads to more rapid recovery from disaster. This how-to-do-it manual teaches people how to build these new roofs.The slurry is painted or brushed onto the fabric, and put on thick enough to work down through the fabric layers. ... They remain stable in Portland cement, and resist the penetration of water, hence provide concrete with good freeze-thaw resistance, and low ... If you are working with sand which already has a moisture content of 7 percent, then you do not need to add the latex milk to get a workable mix.
