This Paper presents a study of the modification as a result of weathering of the behaviour of mudstones from the Keuper Marl series. These soils have previously been heavily overconsolidated and contain considerable proportions of silt-sized aggregations of clay-sized particles. A classification scheme is presented which recognizes one unweathered and three weathered zones, and based upon these four zones a study is made of the influence of weathering on index properties, stress–strain relations, peak and residual effective stress parameters and consolidation behaviour. It is concluded that many of the soil properties that result from overconsolidation are modified by the weathering process, leaving the soil in a pseudo-overconsolidated state similar to that obtained when soils are remoulded at water contents below the liquid limit.

These proceedings are a result of the collective efforts of Committee 544 on Fiber Reinforced Concrete and Committee 549 on Ferrocement and Other Thin Reinforced Products. By AC1 Committee 544 definition, fiber reinforced concrete is concrete made primarily of hydraulic cements, aggregates, and discrete reinforcing fibers. This definition does not include a provision for concretes reinforced with continuous meshes, woven fabrics, or continuous fiber networks.
Therefore, to address all potential types of fiber reinforced concrete, both AC1 Committees 544 and 549 cosponsored a technical symposium. Onginal papers for this symposium were presented at the AC1 Conventions in Boston, March 1991, and in Dallas, November 1991. The papers were reviewed by members of both AC1 committees as well as members of the international community of experts on fiber reinforced concrete. These original, reviewed, and revised papers constitute this AC1 Special Publication. The editors gratefully acknowledge AC1 Committees 544 and 549, the reviewers, the authors, Dr. Gordon B. Batson (symposium Co-chairman and then Chairman of AC1 Committee 549), and the staff of AC1 who have made this volume a timely contribution to the awareness and growth of fiber reinforced concrete.

Admin and the forum staff decided to downgrade all users having less than 3 posts in forum and to move they in a new group named Need Activation. Don't forget, we don't count any post (as Happy New Year and alike).
All users in this group can subscribe to one of Yellow or Green Subscriptions (1 year or 2 years).
We decided to exclude from the free use of forum all users spending the time here and only leeching. Some users think if they login in forum every week they are active and this is enough for being a member of the forum (we received such messages from some disappointed users). As I told to one of users, it's a great honor for us if he login, download and exploit only the forum but it's not enough.
Every user must if he can't post a new thread in software or books sections at least to add a mirror to an existing link, can help users in Engineering Problems or Software Problems. An engineering forum is a place to share knowledge not only to take from others.
We know the posts count sometimes give more than the real number and every time we will see user having more than 2 posts but his posts are useless, only requests and noting else he will be downgraded even if the system doesn't move him automatically
in the Need Activation group.
We have here many users with dozens of requests and nothing else. You are in our sight and if you don't want to be downgraded this is the time to become active.
Active is not posting garbage (the only result will be warnings) but to contribute and share with others.
If you want to be inactive and only to exploit this forum you must pay because the forum costs money to Admin and we the active users don't like to wait and to receive errors because the forum is crowded by leechers increasing the load in server.
We, me and my colleagues, have an intent to extend the range of our laboratory including some test of soils. I have to find some standards describing the mentioned tests.
Unfortunately, I couldn't find all of them...So, I need your help again. It is not urgent. The missing standards which I need are:
1. BS ISO 10390:2005 Soil quality. Determination of pH
2. BS 7755-3.10:1995, ISO 10693:1995 Soil quality. Chemical methods. Determination of carbonate content. Volumetric method
3. BS 7755-3.8:1995, ISO 10694:1995 Soil quality. Chemical methods. Determination of organic and total carbon after dry combustion (elementary analysis)
4. BS 7755-3.11:1995, ISO 11048:1995 Soil quality. Chemical methods. Determination of water-soluble and acid-soluble sulfate
5. BS 7755-3.7:1995, ISO 11261:1995 Soil quality. Chemical methods. Determination of total nitrogen. Modified Kjeldahl method
6. BS 7755-3.4:1995, ISO 11265:1994 Soil quality. Chemical methods. Determination of the specific electrical conductivity
and optionally (if it is possible):
7. BS ISO 11709:2011 Soil quality. Determination of selected coal-tar-derived phenolic compounds using high performance liquid chromatography (HPLC)
dear alll
please can you provide me with the solution manual of Design of Reinforced Concrete (7th ed) By Jack C. McCormac & James K Nelson as i need it
many thanks

Abstract:
A high strength gypsum in combination with sand has been investigated extensively as a potential material for simulating concrete in small scale models of concrete structures. Similitude requirements for a material to be used in model studies are discussed briefly. Tests for determining the appropriate physical properties of a number of mixes are described. It is shown that the behavior of model gypsum mortar is very close to that of the prototype concrete and that it has several advantages over model cement mortars. Size effects as related to compressive and tensile strength are studied; a surface sealing technique is used to reduce size effects to a low level. Charts are presented to facilitate proportioning of different strength mixes, and references are given to a number of successful applications of the gypsum mortar in model studies.

For long-span bridges, wind action is a dominant factor in their safety and serviceability. A large number of long-span bridges have been built in Japan over the past 30 years, and tremendous amounts of research and technical development have been accomplished in wind-resistant design. This book is a compilation of the results of active research and development. Wind-resistant design standards generated in Japan are described in the first few chapters. Then comes information such as design wind speed, structural damping, wind tunnel tests, and analyses, which provide the basis of the design standards. Wind-induced vibrations and their control of girders, towers, cables, and other features are explained with examples of field measurements. Comprehensive listings of Japanese experience in vibration control are also presented. Because achieving particularly dynamic safety against wind is still not an easy task, these data and information will be valuable assets for the wind-engineering and bridge-engineering communities.
