Date: 7/1/2013. Abstract: Five test methods were evaluated that assess the stability of fresh self-consolidating concrete (SCC): the visual stability index (VSI) test; column segregation test; rapid penetration test; sieve stability test; and surface settlement test. These tests were performed on nine precast, prestressed-suitable SCC mixtures ...

SCC can be placed with chutes, buckets and pumps. Pumping is the most common method of SCC placement because of excellent flowability without segregation (Roussel et al., 2007).Fig. 3.3 shows the pumping of SCC from a truck using a crane pump at a building site in Melbourne, Australia.

Cutaneous squamous cell carcinoma (SCC) is a common type of keratinocyte cancer, or non- melanoma skin cancer. It is derived from cells within the epidermis that make keratin — the horny protein that makes up skin, hair and nails. Cutaneous SCC is an invasive disease, referring to cancer cells that have grown beyond the epidermis.
