| ABSTRACT |
|
Investigation for the high strength grouts using ordinary cement mortar, melamine formaldehyde condensate (MFC) with various admixtures was carried out. The physical properties of the grouts were investigated through the observation of the microstructure and the application of fracture mechanics. When the lime stone and fly ash was added with 6 wt% to the grouts, the compressive strength was about 72 MPa, 69 MPa respectively, and the flexural strength was about 11.9 MPa, 11.4 MPa respectively, the Young's modulus was about 4.3 GPa, 3.9 GPa, and the critical stress intensity was about 7.3 |
