“…Additives and admixtures play an important role in the production of more durable grouts than those that can be obtained using neat cement suspensions, increasing the effectiveness of grouting (Anagnostopoulos, 2005;Cambefort, 1977;Mollamahmutoglu and Yilmaz, 2011;Nonveiller, 1989).…”

The main objective of this comprehensive laboratory project was to investigate the potential use of acrylic latex to improve the physical and mechanical properties of thick superplasticised cement grouts. Experiments were conducted using different acrylic latex dosages with cement grouts that were prepared with water to cement ratios of 0·5, 0·4 and 0·33. The results indicated that the addition of acrylic latex of up to 5% significantly increases the 28 and 90 d strength, despite an extension of the setting time. The bleeding and resistance to acid attack of acrylic latex modified grouts were significantly improved. Grouts containing acrylic latex had much a higher viscosity and yield stress than the un-modified grouts. However, acrylic latex reduces the viscosity and yield stress of grouts that were prepared with water to cement ratios of 0·5 and 0·4 when added in small amounts. Based on the experimental results, nonlinear regression analysis was performed to correlate the physical and mechanical parameters of the acrylic latex modified grouts and the descriptor variables.

Abstract. With the arises of environmental conscious, the usage of vertical garden system has become more popular in urban cities. Citizens can enjoys the benefits of energy and cost saving besides ornamental effect. More investigations have been conducted on green facades led to the cities ecological enhancement.However, limited plants species can be planted for green facades systems as this system does not provide sufficient soil and nutrients for common plants. Alternative plantation methods such as planted box and felt system required additional maintenance attention. The idea of using clay composite which consists of nutritious soil, water absorbing polymer and flexible cement clay potentially become alternative vertical greenery systems that offers economic and sustainable plantation platform for more variety of plants.The fabricating of clay composite involved three processes, they are: mixing, moulding and drying. Physical properties characterisation (density, pH, compression test, aging test and water immersion test) were tested on the dried fabricated clay composite to ensure their sustainability in tropical climate. The results showed that clay composite with 1.5 wt% of cement and 0.3 wt% superabsorbent polymer shows optimum water absorbing properties. This system are expected to enable more agriculture activities in urban living.

The penetration grouting is very widely used in geotechnical engineering nowadays, but the slurry diffusion radius is not long enough because of low grouting pressure. The vacuum grouting method is proposed to solve this problem. However, there is no diffusion theory model of vacuum grouting, which makes the practical application lack scientific basis. In this paper, the distribution law of vacuum negative pressure in soil is deduced. Then, the boundary conditions of Maag's spherical diffusion model are modified by the vacuum pressure distribution law. After that, the vacuum modification model is deduced. Finally, Maag's model and modified model are analyzed according to a published experiment, which proves that the vacuum modification model is suitable for predicting the slurry diffusion of vacuum grouting. The proposed model provides a reference for the theoretical study of vacuum grouting.
