The analysis was performed using a novel approach to visualize complex interplays by a clustering and data reduction scheme. In addition, solubility and structural integrity were measured and confirmed the obtained results. PMID: 32198550 [PubMed - as supplied by publisher] (Source: Bioprocess and Biosystems Engineering)

Producers of designated concrete must have in place a system of third party accreditation for their production control and product conformity. This accreditation allows the customer to be confident that concrete supplied with be suitable for the required application.
An accurate optimal design of laminated composite structures may present considerable difficulties due to the complexity and multi-modality of the functional design space. The Big Bang – Big Crunch (BB-BC) optimization method is a relatively new technique and has already proved to be a valuable tool for structural optimization.
(b) Find out the workability in terms of slump for selected water-cement ratio for a particular job. (c) Find out the maximum size of coarse aggregate, which is desired to use, or which is available.
Nearly all of prestressed concrete is precast as are concrete blocks. Concrete blocks are made in various weights and sizes and they are used to make about two-thirds of masonry walls in the US. Engineers have designed kinds of concrete for certain uses. Air
Mix design is a process of determining the right quality materials and their relative proportions to prepare concrete of desired properties like workability, strength, setting time and durability. While following a mix design is advised to optimise the material ...
The aims of the design of the offshore concrete structure and its elements are to: — — — — Withstand loads likely to occur during all temporary, operating and damaged conditions. Maintain acceptable safety for personnel. Have adequate durability against deterioration during the design life of the offshore concrete structure.

The story of the development of translucent concrete shows the stony road from the i dea to the product: however much the idea of the material may fascinate the architect, the build ing materials industry works purely according to economic criteria governed by batch sizes, sales and profits.
Concrete is made from cement, sand, gravel and water. In making concrete strong, these ingredients should usually be mixed in a ratio of 1:2:3:0.5 to achieve maximum strength. That is 1 part cement, 2 parts sand, 3 parts gravel, and 0.5 part water. (See figure 6).
Portland cement, concrete, or mortar can be mixed with water and spread over well-compacted bases to cover and to seal selected disposal sites. Bituminous concrete or mortar composed of 7-10 percent asphalt is another rigid cover material that can be used effectively to pave over the surface of a landfill.

concrete armour units: prefabricated concrete units for armouring. In relating properties to functions, it is useful to distinguish the following three types of property that relate to different phases in the life cycle of armourstone.
Quantitative Survey and Structural Classification of Hydraulic Fracturing Chemicals Reported in Unconventional Gas Production
The advantages of the different objectives that consider the production rate, recovery yield or solvent consumption to achieve both productive and economical separations are discussed. Guidelines are given how to select the essential column design and experimental parameters to be optimized.

batch weight (lbs) based on saturated surface dry condition. The design batch weights are added to obtain the total weight of ingredients required to make 27.00 ft3 of concrete at 6.5% target air content. Table 3.4 illustrates tabulation of the example problem.
Concrete Mix Design, Form Design, and Engineering George E. Thomas, PE Course Content 1. INTRODUCTION Concrete is one of the most versatile, economical, and universally used construction material. It is among the few building materials produced directly on the job by the user. To know proper mix, it is important for the user to

Concrete compositions K, C1, C2, C3 were selected depending on the characteristics of raw materials, by implementing computational experimental methodology and by using tables, diagrams and nomograms. The selected class of the concrete compressive strength was C30/37, mobility 3 cm.

James Turrell has dedicated his practice to what he has deemed perceptual art, investigating the materiality of light. Influenced by the notion of pure feeling in pictorial art, Turrell’s earliest work focused on the dialectic between constructing light and painting with light, building on the sensorial experience of space, color, and perception.
Australian company InQuik has developed a unique method of building bridges which can be implemented quickly using only low-skilled labour. The globally patented technology utilises Magnelis® from ArcelorMittal Europe – Flat Products to create the formwork of a bridge, which is then filled with concrete to create the bridge deck.
The fresh concrete is placed carefully in the steel test container. Compaction must be avoided. When the container is full to overflowing, the concrete is smoothed flush with the edge without vibration. The concrete is then compacted, e.g. with a poker vibrator (max. bottle diameter 50 mm). After compaction the distance between the concrete
Concrete strength Many factors influence the rate at which the strength of concrete increases after mixing. Some of these are discussed below. First, though a couple of definitions may be useful: The processes of 'setting' and 'hardening' are often confused: Setting is the stiffening of the concrete after it has been placed. ...
complex to predict, and few design recommendations are available in current stand-ards for timber structures. In this context, the paper focuses on the assessment of the typical buckling behaviour of vertically compressed timber log-walls. The effects of various mechanical and geometrical variables such as possible load eccentricities
context of the cave, bifacially reduced tools could be used for butchering and hide scraping, woodworking, cutting organic fibers for cordage and other perishable artifacts, and scraping. There were 26 bifaces recovered from High Rolls Cave (Fig. 8.1). The material represented in the assemblage was chert. These bifacial tools
