Concrete microstructure / by Roy, D. M.(CARDINAL)324792; Idorn, G. M.(CARDINAL)324793; Pennsylvania State University.Materials Research Laboratory.(CARDINAL)324791; Strategic Highway Research Program (U.S.)(CARDINAL)298325;
Includes bibliographical references (pages 161-166).Executive summary -- Mixing, rheology, strength, packing -- Hydration, maturity and curing -- Microstructure -- Porosity, pore structure, permeability and their relation to durability -- Revisions to test methods -- Work cited -- Bibliography -- Appendices.Durability of concrete in highway systems is a problem of national concern. In order to better understand the mechanisms which intrinsically control durability in highway concrete, it is necessary to define and understand those factors which impact concrete microstructure which is a consequence of both its formulation and the processes taking place during mixing, placing and curing. This report documents an investigation of those variables which control cement hydration and consequent microstructural development.Performing organization: Pennsylvania State University, Materials Research Laboratory, under contract no.

Cement paste aggregate interface microstructure / by Roy, D. M.(CARDINAL)324792; Strategic Highway Research Program (U.S.)(CARDINAL)298325; Pennsylvania State University.Materials Research Laboratory.(CARDINAL)324791;
... contract no.This report describes research into the nature of the interfacial region in concrete. The interfacial region, considered more porous than the paste itself, could act both as a localized 'weakness' where fractures are initiated, and as an avenue of attack for aggressive chemical agents. Computer simulations of particle packing against an aggregate surface show that it is the efficiency by which particles pack against the aggregate during mixing which influences the nature and strength of the interfacial region which develops over time. Also, simulation results suggest that the degree of flocculation and the intensity of mixing are not entirely independent variables.Includes bibliographical references.Abstract -- Executive summary -- Introduction -- References -- Interface simulation model -- Microstructure of concrete interfaces -- Microstructure of engineered interface samples -- Microstructure of paste/sand interfaces in mortars -- Summary and conclusions.

The secrets of sand : a journey into the amazing microscopic world of sand / by Greenberg, Gary,1944-author,photographer.; Kiely, Carol,author,photographer.; Clover, Kate,author,photographer.;
"From the beach to the moon--explore the incredible hidden world of sand, seen through a microscope.To the naked eye, the tiny particles that make up sand are less than inspiring. Under the microscope, however, it's a completely different story. Looking at sand under extreme magnification, we quickly find ourselves immersed in a new world of brilliant colors, organic shapes, and the stunning patterns of nature.Every grain of sand is a snapshot in time: Each grain originated somewhere and is headed somewhere else. Biogenic sands often contain fragments of the hard tissues from marine organisms such as shells, corals, sponges, sea urchins, forams, and bryozoans. When these organisms die, the hard tissues that are left behind erode into some of the most spectacular grains of sand imaginable. In this book, deep-focus microscope photography, x-ray images, and high-resolution scanning electron microscopy reveal their secrets.The Secrets of Sand is a virtual tour of sands from across North America. It shows their origins, the environmental forces that have acted upon them, and their journey from bedrock or invertebrate shell to the fine particles that, in countless billions, form our familiar beaches and dunes. It then moves on to an exploration of lunar sand, which has been formed under such alien conditions that it has no terrestrial counterpart. The Secrets of Sand is an amazing voyage of discovery in the ancient past--and the dynamic present--of the earth and our nearest neighbor"--
