Dear Sai Pavan,
Many new technologies are changing the way we build and what we build with concrete.
1. Adding optical fibers to a concrete mix generates translucent concrete. This “see-through” development is changing the perception of concrete’s opaque mass.
2. Reactive powder concrete is extremely workable, durable and yields ultra-high strengths without using coarse aggregates. Reaching compressive strengths of 30,000 pounds per square inch (psi), this new-age concrete also has tensile strength with the inclusion of steel and synthetic fibers. Read more on reactive powder concrete.
3. Self Consolidating Concrete (SCC) eliminates the need for mechanical consolidation and yields a smooth surface finish without mix segregation. Read more on self consolidating concrete.
The field approached by you is very interesting and also vast, so more research can be done in this regard. It's very interesting topic. The following article link may help you for your kind information.

Flow with Show: Self-Consolidating Concrete Offers New Opportunities for Architectural Concrete
Architectural concrete is a hot topic. Defined by the American Concrete Institute as “concrete which will be permanently exposed to view and which therefore requires special care in selection of the concrete materials, forming, placing and finishing to obtain the desired architectural appearance,” it is showing its face everywhere. Examples of applications are buildings and transportation structures like bridges and highway sound/barrier walls. Delivery methods include cast-in-place, precast, and tilt-up, and in every case, good appearance is essential. Achieving good surface characteristics requires thorough consolidation of the fresh concrete and thoroughly filled forms. Fortunately, this also leads to a durable material because water, precipitation, and aggressive chemicals or ions are shed by the surface skin.
Conventional concrete is placed using vibrators to fill the forms. Self-consolidating concrete (SCC) is a big step forward in fool proofing that procedure.
Self-Consolidating Concrete
The construction industry has always longed for a high-performance concrete that can flow easily into tight and constricted spaces without requiring vibration. The need for this technology has grown as designers specify more heavily reinforced concrete members and ever more complex formwork. Honeycombing or exposed reinforcement in structural walls or columns is a constant concern in these structures.
SCC Formulated with White Cement
Architectural expression in concrete means different things to different people. Some designers appreciate concrete for its unadorned appearance. So gray portland cement concrete can receive architectural treatment. Some designers want to use color to express aesthetics, and white portland cement is available to create white or colored concrete. Much of the experimental work to date on SCC has focused on gray cement, but there are opportunities for white cement formulations.
Recently, image based non-destructive performance measurement of special concretes are very popular, in addition to the new materials being used. I would suggest the publication below:
