Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Strength of Fine-Aggregate Concrete I. Introduction During the meeting of the Texas Road Builders' Association in Austin, February 18 to 20, 1920, the general discussion of concrete construction developed the facts that in certain sections of Texas the available local concrete aggregate is rather fine; that coarse aggregate can be secured only at a very high cost; and that, under such condition, it might be well to prepare concrete without the use of coarse aggregate, increasing, when necessary, the cement-aggregate ratio so as to secure the desired physical properties in the concrete. This condition suggested the need for an investigation to determine how the compressive strength of the concrete varies with the relative quantity of cement when the maximum size of the aggregate used in the preparation of the concrete is considerably smaller than that usually employed in concrete construction. Accordingly, four series of tests were made in the manner and with the results described in this bulletin. II. Scope Of The Investigation The object of the investigation was to determine the ultimate compressive strength at 28 days of concrete prepared of fairly well graded aggregate the maximum size of which varied from one-eighth to one-half inch. In addition, tests were made for the purpose of determining something of the effect of additional water on the strength of the concrete, and also the effect of rodding the concrete in which excess water was used. A few tests were made for the purpose of comparing the strength of 6 by 12-inch cylinders with that of the 2 by 4-inch cylinders used for the majority of the specimens.

This book was released on 2016-08-31 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Influence of Temperature on the Strength of Concrete Cement. All of the test specimens were made with Universal portland cement. Samples were taken at the beginning of each series and were tested for fineness, soundness, and tensile strength. The cement passed the requirements of the Standard Specifications of the American Society for Testing Materials. The tensile strength tests of neat and mortar briquettes made of a sample of the cc ment used in Group III of the 1914 Series gave average values of 542 and 609 lb. Per sq. In. For the neat cement at seven and twenty eight days, respectively; and 174 and 295 lb. Per sq. In. For the 1: 3 mortar at seven and twenty-eight days, respectively. Sand. The sand used came from a deposit of glacial drift near the Wabash River at Attica, Indiana. The sand was clean and well graded. The sand of the 1913 Series was somewhat coarser than that of the 1914 lot. The sand used in Group III - 1914 Series - gave a density of a specific gravity of and contained 32 per cent voids.

This book was released on 2017-11-20 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Effect of Clay on Strength of Concrete The aggregate of concrete may consist of any hard material, but for most purposes either broken stone or gravel is used. While it is conceded that an aggregate of broken stone makes a stronger concrete than does an equal proportion of gravel, it is often ad visable for the sake of economy to choose the gravel concrete. If then, gravel is used, it is important that that gravel be selected which will give the greatest economy. The three qualities of gravel generally considered to be of most importance in making concrete are durability, fineness, and cleanness. Durability depends wholly upon the kind of rook compos ing the available gravel, and cannot be controlled by the engineer. However, durable gravel may be recognised by proper examination andif needed for special purposes may be obtained. Likewise the prob er fineness of gravel is agreed to be that which will give minimum voids. In regard to cleanness, however, there is so little relia ble information that engineers disagree radically as to the degree of fineness which may properly be demanded.

Book excerpt: Excerpt from Sharing Strength of Concrete: Thesis The recent growth in the use of concrete has created a great demand for more information concerning its strength under many conditions and its various methods of failure. Modern competition in structural work has naturally been the cause of much investigation along lines of economical design, so that in the last few years reinforced concrete has taken a prominent place among building materials.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Concrete Strength During Construction Three types of concrete specimens were used. For the compressive and splitting tests, conventional 6 x 12 in (15 x 30 cm) cylinders were cast in waxed cardboard molds. For the nde tests, unreinforced 3 ft x 5 ft x 5 in thick m x m x 140 mm) slabs were cast in oiled wood forms. The pull-out specimens for the relative bond - strength tests consisted of a 48 in m) long No. 6 in or 19 mm) deformed reinforcing bar ksi, or mpa yield) cast in a 6 x 8 in (15 x 20 cm) waxed cardboard cylinder mold. Figure 1 shows the pull-out specimen and mold. The specimens were made so that the bar was bonded to the concrete for a length of 6 inches cm) in all specimens. The pull-out molds were set up for casting in gang racks holding 6 specimens each. The racks were designed to rigidly hold each bar in a Vertical position during the casting operation and during curing. The metal bottom of each cylinder mold had a hole drilled in it so that the bottom end of the bar would extend into a hole in the plywood base of the rack. A plastic furniture tip over the end of the bar sealed the hole in'the bottom of the mold and protected the end of the bar. The concrete cylinder of each pull-out specimen was reinforced with a in cm) diameter cage made of 2 in x 2 in (5 cm x 5 cm) welded steel wire mesh of 16 gage in or mm).

Book excerpt: Excerpt from Influence of Temperature Upon the Strength of Concrete A large number of concrete structures are built during the late fall and early spring when the temperatures are low and usually varied. Very little information exists regarding the effect of var iations of temperature upon the setting action of concrete. Such information would be of the greatest value to contractors, for with it the time can be determined when the concrete will have gained sufficient strength to warrant the removal of the forms. Many of the Concrete failures of the past have been attributed to the exist ing temperature conditions and the lack of knowledge due to them.

Book excerpt: Excerpt from Reinforced Concrete Field Handbook Cement as it is received on the work, is well known as a fine, almost impalpable grayish powder. The one necessity, which on construction work becomes almost second nature, is to keep the cement dry in handling and storing. Portland Cement is an artificial mixture in certain well defined proportions established by practice, of lime, silica, alumina and other substances in minor quanti ties. Lime, mixed and calcined with clay, has the property of setting under water. A natural cement is made from rocky conglomerates which may contain the approximate quantities required, and which varies in its properties as the constituents of the natural de posits vary in proportion. Portland cement on the other hand is an exact artificial composition in pro portions determined by analysis and experiment.

Book excerpt: Excerpt from Investigation of the Effect of Heat Upon, the Crushing Strength and Elastic, Properties of Concrete The concretes used have included trap, limestone and cinder, and were usually 1-2-4 or 1-2 5 mixtures. The reports of numer ous tests of this character were examined and in most instances the concrete stood the heat and subsequent loading well, but the results were general and referred to the quality or resistance of a particular construction rather than to specific data regarding the concrete itself. Large numbers of tests of compressive strength and elastic properties have been made upon concrete of various composition and after different preliminary treatments, but no records were found in which the concrete was heated prior to testing.
