Abstract

A combination of Energy Dispersive X-ray Fluorescence (EDXRF), Fourier Transform Infrared (FTIR) Spectroscopy, X-Ray Diffraction (XRD) and Thermogravimetric Analysis (TGA) provided a detailed chemical and mineralogical characterization of rubble mortars inside a coral stone veneer wall of 19th century Spanish Colonial Period structures in the Philippines. Evidence of possible raw materials (seashells/corals and beach sand), manufacturing techniques (dry and wet slaking), and type of lime binder (aerial and slightly hydraulic), was reported. Results of this study provides a needed baseline scientific data for promoting the proper restoration and conservation of heritage structures in the Philippines.
