摘要：

The addition of methylcellulose (0.4% by weight of cement) or latex (20% by weight of cement) to cement paste gave similarly significant increases of the shear bond strength between stainless steel fiber acid cement paste, in spite of the low concentration of methylcellulose compared to latex. The methylcellulose addition did not affect the contact electrical resistivity between fiber and cement, whereas the latex addition increased this resistivity. Hence, for low cost and low contact resistivity, methylcellulose is preferred to latex. For a given cement paste composition, the bond strength increased linearly with the contact resistivity.
