Chemical admixtures are used to change the houses and behavior of clean and hardened concrete. they permit extra monetary development and the success of exact homes akin to excessive energy or toughness. This booklet offers new learn info from a world RILEM Symposium on six major subject matters: workability, environment, power, toughness, different houses and expertise.

A table vibrator, such as that used in Japan, was used at the bottom of the container. 1Hz. The test set-up is shown in Fig. 3. The accelerations of container at five locations were measured as shown in Fig. 4 and measured mean values are summarized in Table 3. Admixtures for concrete 28 Fig. 3. Rotating fan type rheometer Fig. 4. Locations and directions of acceleration gages Dynamic rheological properties of fresh concrete with chemical admixtures 29 Table 3. 5 Pore water pressure measurement Locations of pore water pressure gages are shown in Fig.

Two water pressure gages were set up in the middle of container at two levels of 7cm and 17cm from concrete surface. Fig. 5. 1 Dynamic rheological properties of mortar with chemical admixtures Admixtures for concrete 30 The measured longitudinal wave velocity of fresh mortar with chemical admixtures are summarized in Fig. 6. 03% per cement content and water cement ratio is 50%. 75% per cement content respectively. 4kg/m3 of non-segregation-in-water agent (NSIW) and water cement ratio of M1 and M2 are 40% and 50% respectively.

In the future, we want this new superplasticizer (Mighty 2000) to be used throughout the world, and to contribute to the progress of concrete technology. 239 (1979). Okada. 10 (1984). Y (1963). 72 (1985). KOJIMA Department of Civil Engineering, Ritsumeikan University, Kyoto, Japan Abstract A basic experimental investigation was carried out in order to obtain an effective and rational method in consolidating fresh concrete with chemical admixtures by using vibrator. The rheological properties of fresh concrete during vibration were examined experimentally.
