what kind of tests should perform on self consolidated cement paste incorporating suplementary cementious materials such as fly ash, rice husk, etc. i am using differnt kind of materials for the measuring the durablity of the self consolidated cement paste after using other differnt materials. so what kind of test should i perform on such material
For durability point of view, water absorption is essential parameter so water permeability, sorptivity and chloride ion permeability test such as RCPT should be performed. Apart from these tests microstructure analysis is also desirable as supplementary cementious materials like fly ash rise husk etc were used in the SCC. So SEM images will help in microstructure behaviour of SCC, which also gives the idea about micro crack and voids present in concrete.
From my experience, the most important are the tests of consistency and its maintenance over time (outflow funnel) we measure the time and flow as well as the lack of segregation
with due respect dear fellow researchers i am not looking for tests for workability consistancy or outflow. i am looking for checking the durability of the cement past incorporated with differnt supplementary materials. i wan to find in depth behaviour of cement paste when it mix with other materials so for that purpose i need to performe different tests to find the patterns of bonds just like chemical analysis petrography etc
Additionally, an important element is to check the compatibility of the chemical admixture with cement and the filler additive
An interesting paper on consolidation and desiccation of clay slurries

There must be chemical analysis test of materials blended with cement, and along with chemical analysis Compressive strength with frequent interval of 14 days minimum 7 set of interval required for the test to understand the bond of different material compatibility with cement, with the result one can make a strength gaining graph and can be comparative study easily with normal blending processes.
