TLDR
In this article, the performance of lightweight concrete under different w/cm ratio and different cement paste content was compared with self-consolidating lightweight concrete (SCLWC), and the test results indicated that the 91-day compressive strength of SCLWC is up to 56 MPa when cement content is 386 kg/m3 and water content is 150 kg /m3.About:

Effect of aggregate type on properties of hardened self-consolidating lightweight concrete (SCLC)
TL;DR: In this paper, the effects of aggregate type on the physical and mechanical properties of hardened self-consolidating concrete produced with lightweight aggregate (SCLC) were investigated, and the results showed that SCLC with LWA in lower unit weight has lower mechanical and physical properties except for thermal properties when compared to properties of SCC.

Building Durable Structures in the 21st Century
TL;DR: The primary greenhouse gas is carbon dioxide and, during the 20th century, its concentration in the environment has risen by 50 percent as discussed by the authors, and therefore, the construction industry needs to determine how future infrastructural needs can be met without further increases in the production of cement and steel.
