Concrete for Road Pavements ScienceDirect

01/01/2017· Concrete with these two additives used in rational quantities is characterized by 58-59% increase of compressive strength and 83-91% increase of tensile strength in bending, with coefficient of crack resistance rising by 17-20%. The concrete abrasion corresponds to the G1grade of concrete and the concrete freeze resistance to F 2600 grade. The concrete water absorption is reduced by 40%. This increases the concrete density. Corrosion resistance of the modified concrete

Behavior of Concrete with Polymer Additive at Fresh and

01/01/2011· One of such material comes from paint factory (waste latex paint), which at the moment being tried as additive by many researchers. This paper presents results of laboratory work carried out on emulsion by-product polymer in order to evaluate its performance as an additive in concrete. Series of concrete mixes containing 1%, 2%, 3%, 5% and 10% polymer contents by weight of cement were

Effect of Pozzolanic Additives on Structure and Chemical

01/01/2013· Abstract. This study investigates relationships between concrete containing pozzolanic additive and mineralogical composition, porosity and chemical durability to sulphate ion containing solution. As pozzolanic admixtures micro and nano size silica and biomass ashes were used. The investigation was carried out by X-ray diffraction, Hg absorption porosimetry and optical microscopy.

01/02/2017· The concrete and abstract conditions were conducted on two separate days. The possible range of scores for each principle (commutativity and complement) in each condition (concrete versus abstract) was 0–6. In all trials, feedback was not given. The internal consistencies of the additive reasoning measures were satisfactory (Commutativity-concrete: Cronbach's α = 0.73; Commutativity

Balancing the Concrete and the Abstract Educational

By moving between concrete and abstract examples, teachers enable students to gain deep understanding of the core concept, apply their new knowledge in different situations, and acquire true ownership of what they have learned. This approach, which is widely applicable across various disciplines and age groups, is just one example of a research-based practice that, coupled with other

Mineral Admixtures-Types,Advantages and Uses

As we know that, usually we do not make any construction without any concrete additives in a construction site for getting better improvement in properties. The use of pozzolanic or mineral admixtures is old as that of the beginning of concrete construction. The use of mineral admixtures modify the fresh and hardened concrete properties. The mineral admixtures are also called supplementary

Abstract vs. Concrete Syntax Trees Eli Bendersky's website

16/02/2009· CSTs Concrete Syntax Trees (a.k.a. Parse Trees) and ASTs Abstract Syntax Trees (a.k.a. Syntax Trees) are two terms that come up a lot in compiler & parser nomenclature. However, it is not always understood what is the difference between the two, because they are closely related. In this article I attempt to explain the difference, at least for myself. Concrete Syntax Trees. CSTs are a
