This work aimed to investigate the possibility of using binder obtained from calcined laterite and phosphoric acid as a novel stabilizing for the manufacturing of compressed earth bricks (CEB). Various proportions of binder from up to 20 wt% were used to stabilize the soils. Fourier Transformed Infrared Spectroscopy (FTIR), X-ray diffraction (XRD) thermal analysis (TGA-DSC), Scanning Electron Microscopy (SEM), water absorption and compressive strength tests were used to characterize the obtained products. The results showed that CEBs developed are highly resistant (similar to concrete) with dry compressive strength ranging from 17 MPa to 38 MPa and wet compressive strength from 6.3 MPa to 16.9 MPa. All the CEBs are also water-resistant and the water absorption was between 9.36-14.18 %. The increase of the binder content improves the performance of the compressed earth bricks. The new binder developed, which is based on the ferro-silico-aluminophosphate network, is effective for the stabilization of the lateritic soil for producing compressed earth bricks.

这项工作旨在研究使用从煅烧红土和磷酸中获得的粘结剂作为新型稳定剂来制造压缩土砖（CEB）的可能性。高达20 wt％的各种比例的粘合剂用于稳定土壤。使用傅立叶变换红外光谱（FTIR），X射线衍射（XRD）热分析（TGA-DSC），扫描电子显微镜（SEM），吸水率和抗压强度测试来表征所得产品。结果表明，开发的CEB具有很高的抵抗力（类似于混凝土），干抗压强度为17 MPa至38 MPa，湿抗压强度为6.3 MPa至16.9 MPa。所有的CEB都具有防水性能，吸水率在9.36-14.18％之间。粘合剂含量的增加改善了压缩土砖的性能。基于铁-硅-铝磷酸盐网络开发的新粘合剂有效地稳定了用于生产压缩土砖的红土土壤。
