Four different consolidants for adobe buildings conservation were synthetized and evaluated. Adobe bricks materials tested from several Mining Haciendas of the seventeenth and eighteenth centuries located in Guanajuato, Mexico; these materials were characterized using XRD analysis, granulometry, porosity, moisture content, and mechanical resistance. The four consolidants synthetized are formulations based on TEOS (F1); TEOS with silica nanoparticles (F2); TEOS with PDMS-OH (F3) and hybrid consolidant formed by TEOS, PDMS, and nanoparticle silica (F4). The consolidants were tested and evaluated by porosity changes, absorption, and durability. The results show that colloidal silica improves the fulfill porosity by TEOS gels and the PDMS improves the flexibility on TEOS gel avoiding the crack. Thus, the addition of both components to TEOS gel results as an excellent consolidant treatment to adobe materials.

合成并评估了四种用于土坯建筑保护的固结剂。在位于墨西哥瓜纳华托的17和18世纪的几个采矿庄园对Adobe砖材料进行了测试；使用XRD分析，粒度分析，孔隙率，水分含量和机械强度对这些材料进行了表征。合成的四种固结剂是基于TEOS（F1）的配方；含二氧化硅纳米粒子的TEOS（F2）; 带有PDMS-OH的TEOS（F3）和TEOS，PDMS和纳米颗粒二氧化硅（F4）形成的混合固结剂。通过孔隙率变化，吸收率和耐久性来测试和评估固结剂。结果表明，胶态二氧化硅提高了TEOS凝胶的充实孔隙率，PDMS改善了TEOS凝胶的柔韧性，避免了裂缝。从而，
