Abstract

<p>We investigated the structure of solidified sodium silicate solidified with cement using Raman spectroscopy, X-ray diffraction measurements, and 29Si solid MAS NMR measurements. Raman spectroscopy and NMR measurements confirmed that alite was consumed in the early stage of the reaction, and sodium silicate promoted the reaction, resulting in an intermediate phase consisting of a chain structure containing Q2. Furthermore, X-ray diffraction halo analysis revealed the formation of an amorphous solid derived from tobermorite.</p>
