Introduction In the 21st century, concrete was still widely used as building materials.
Because of the increasingly scarce resources, simply abandoned waste is a tremendous waste of resources [2]. 1 Experimental material and experimental program 1.1 Experimental material and equipment Experimental material come from old building which is made of gratis.
The experimental materials include: The experimental materials include: general 32.5Mp Portland cement which is made in Sichuan Shuangma Cement Co., Ltd, common tap water in Southwest University of Science and Technology, and medium sand.

The nanostructured photocatalysts are the most promising materials for the degradation of toxic dyes.
Micro-Raman Studies Fig. 2 shows the micro Raman spectra of CaTiO3 materials synthesized by microwave irradiation method.
SEM Analysis Fig.3 (a), (b), (c) show SEM image of CaTiO3 materials synthesized by different microwave irradiation time CT10, CT20 and CT30, respectively.
CT20 and CT30 material show the slightly agglomerated morphology compared to CT10 material.
The synthesized materials were analyzed using advanced characterization techniques.
