IMPROVING THE STRENGTH OF METAKAOLIN-LIME BASED BINDER

Improving the strength of metakaolin-lime based binder

Pozzolanic reaction of low-calcium metakaolin (MK) with calcium hydroxide (CH) at ambient temperature in the presence of water forms a series of hydrated phases such as tetracalcium aluminate hydrate (C4AH13), calcium silicate hydrate (C-S-H) and calcium aluminum silicate hydrate (stratlingite - C2ASH8).Stratlingite is the main crystalline phase Or

Failure Mechanism and Dynamic Response Characteristics of Loess Slopes Under the Effects of Earthquake and Groundwater

A large-scale shaking table test was conducted with simulated earthquakes and groundwater to study the dynamic response and instability mechanism of a loess slope with a saturated bottom.By examining the acceleration, dynamic pore water pressure, corresponding soil pressure and observed macroscopic failure behaviour of Pygeum the slope under differ
