Soil-cement concrete can be manufactured by mixing portland cement, water and on-site soil and has been studied by the authors. This study deals with compressive strength and density of soil-cement concrete where the portland cement was partially substituted with fly-ash. Saturated surface-dry condition of on-site soils has never been taken into account in the conventional mix design whereas experiments of determining the saturated surface-dry conditions were carried out with the help of the concept of effective water content to assure the quality and the designed strength. Effects of fly-ash on the strength and density of soil-cement concrete were studied by altering cement-fly-ash ratio, soil-sand ratio, binder-water ratio and age under a constant unit water content

The paper presents a new concept of ultra-filled by studying of classical aggregate filling theory. To resolve the problem involved in mix design with ultra-filled theory, a mix proportion design method of manufactured sand cement concrete is established. By calculation and test, the paper works out the rich plasma factor K1 and K2 of pavement manufactured cement concrete and the experimental result shows that the method is feasible and reasonable.

Concrete Matrix

Concrete is the most used material for the construction in the modern time of infrastructures. Concrete is strong in compression but it is weak in tension and shear. To minimise those problems, fibres were introduced in concrete to enhance its tensile strength and shear strength. In my present investigation, the mechanical properties of fibres reinforced concrete are studied by using steel fibre, glass fibre and polyamide fibre with a different weight fraction of fibres with respect to cement. The mix design of M25 concrete with W/C ratio of 0.42 is prepared and total thirteen mixes included one control mix was prepared and tested in the laboratory. The total quantity of fibres mixed in the concrete are in order of 0%, 0.75%, 1.5%, and 2.25% by weight of cement and one mix contains 0.33% of glass fibre, 0.33% of steel fibre and 0.33% of polyamide. The study shows that the mixed fibres provide better properties in controlling cracks and high strengths than single fibre and concrete without fibre. On increasing the percentage of fibres beyond 1.5%, the strength of the concrete matrix decrease due to mat form of fibres or non-uniform distribution of fibres and also decrease due to non-cohesiveness of the concrete particle to each other.

According to the particularity of the autoclaved cement concrete that partial aggregate could participate in hydration reaction in the process of autoclaving, the optimal gradation of coarse aggregate and the optimal slurry aggregate ratio is studied, and the effect of water reducing agent for fluidity of cement paste is also studied. The optimized mix design of autoclaved cement concrete based on high strength (compressive strength and flexural strength) is done by orthogonal test with four factors (water-binder ratio, type of mineral admixture, amount and sand ratio) and four levels.

The aim of the project is to replace cement with fly ash and course aggregate with Ethyl Vinyl Acetate (EVA) in paver block. In this thesis paver block design is by using cement concrete mixture of mix design M30 which is composed of 10mm coarse aggregate cement and fine aggregate (M-sand).In this thesis the cement is partially replaced with fly ash and partial replacement of EVA with coarse aggregate in paver block at various level of 5, 10, 15, and 20 percentage of its weight. The paver block curing process is done for 7days and 28days. After curing it is checked for its compression strength, water absorption test and densitytest.

Recycling Techniques

This technical paper shows the innovative approach used in the rehabilitation of the runway of the airport of Treviso. Treviso is located in North Italy and lies about 40 km far from Venice. For this reason, the airport of Treviso may be considered the second airport of Venice and receives the low-cost companies. In order to minimize the environmental impact of the rehabilitation project, the materials coming from the demolition of the old runway pavement were completely recycled in the new runway pavement. Several recycling techniques were used such as the cement stabilization of soil, cement treatment of milled cement concrete and cement-bitumen treatment of reclaimed asphalt. This paper shows the technical application of scientific knowledge on pavement recycling developed in Italy in the last decade.
