ABSTRACT All this time, mortar is known to have low resistance when exposed to high temperatures. So that several studies recommend the addition of additives to increase resistance to high temperatures. In this regard, this study aims to examine some of the physical and mechanical properties of mortar with added material in the form of clamshell powder as an alternative cement replacement …
Lightweight bricks are bricks that are made to be lighter. CLC lightweight brick has a density between 400 kg/m3 to 1800 kg/m3. Light brick is now starting to be widely used for wall construction, because it can lighten the load on the foundation. The building blocks of lightweight bricks are cement, sand, water, foam agent, and other added materials such as chemical mixtures. One of the ch…
ABSTRACT The purpose of this study was to examine the application of artificial neural networks to predict the compressive strength of lightweight concrete after exposure to heat, and density before and after exposure to heat. To achieve this goal, an experiment was carried out by testing ligthweight concrete as many as 144 samples. The dimensions of the sample are 10x10x10 cm. Before bein…
ABSTRACT Batang Kuranji is one of the watersheds in the city of Padang. In fact, in the upstream part of the Kuranji watershed, land use/degradation has begun. Changes in land use can lead to high surface runoff, which later can cause disasters such as floods, landslides and land erosion. Land erosion produces fine particles that are carried away by the flow then settles at the bottom of t…

ABSTRACT The development of the times in the field of science continues to increase every year, giving rise to new ideas, especially in the field brick wall construction. The wall construction has new innovations,namelylightweight brick as a substitute for conventional red brick. Lightweight bricks are made by including air bubbles in the mortar mixture, so that the brick weight becomes li…
ABSTRACT The Riau University campus is the largest campus in Riau Province and continues to experience an increase in student admissions which of course will affect the level of arbitrary waste disposal in all places, especially waste disposal in the drainage system. This study aims to determine the level of sedimentation in the drainage network so that it can be used as a reference to det…
ABSTRACT Before the construction of a building, the Budget Plan is one of the main processes carried out to determine the total amount of work costs by outlining each work item starting calculating the volume of work, making a Work Unit Price Analysis (AHSP), making detailed Budget Plans, all of which The calculation refers to the plan drawings, material prices and wages around the constr…
ABSTRACT As an urban area that has growth data that is always growing every year and where infrastructure in urban areas is a reference for success to balance population growth. This research uses rainfall data that has occurred for 10 years obtained from relevant service agencies and conducts a survey in the field to find out the problems that occur. already in the field. After obtaining …
ABSTRACT Concrete is obtained by mixing portland cement, fine aggregate, coarse aggregate, and water with or without the use of additional materials. To obtain a concrete with better strength, then the use of additional materials. One of the additional material admixture such as superplasticizer used is MasterGlenium ACE® 8595. This study aims to determine how big the influence of the add…
ABSTRACT The impact of changing land into residential areas can indirectly damage water catchment areas resulting in inundation and even flooding. Drainage design should pay attention to concepts related to water resource conservation efforts by draining runoff water from infiltration building such as infiltration wells. Infiltration wells are one of the appropriate structures for the redu…
ABSTRACT Street Parit Indah connects with Jalan Pesantren to Jalan Lintas Sumatra so this road is classified as a collector road. Collector road is a road that serves collector transportation with the characteristics of medium distance travel, medium average speed and limited number of access roads. This road is classified as a collector road with two undivided two-lane (2/2 UD) that has l…
ABSTRACT The high speed of vehicles on Jalan Topa Desa Pertapahan Jaya Kampar Regency is an influencing factor in Rigid Pavement Planning, where this road is the main road in traffic in the Petapahan Jaya Village area because this road can be a link from Petapahan to Rokan Hulu. So in this Rigid Planning I get the results of CBR, LHR, and Reinforcing Steel. Where the amount of LHR data is…

ABSTRACT Fly ash bottom ash geopolymer concrete with the addition of portland composite cement aims to make the concrete able to carry out treatment at room temperature. This study aims to examine the physical and mechanical properties of hybrid geopolymer concrete and PCC cement concrete with peat water immersion for 0, 7, 28 and 91 days after 28 days of treatment at room temperature, in…
ABSTRACT Concrete has low tensile strength and large porosity, affecting its mechanical and physical properties. This study aims to examine the mechanical properties and porosity of the concrete. A 28 days immersion and room temperature of blended fly ash concrete with pineapple leaf fiber treated with NaOH were studied. Fly ash substitution in the concrete mixture was 10 percent. The vol…
ABSTRACT Numerical models of irrigation network system planning based on SNI and KP are needed to speed up the irrigation network system planning process. This model is formed with a system from of the Visual Basic Application (VBA) for excel program by algorithmizing all existing equations needed in an irrigation network system planning. This numerical model of irrigation network system p…
ABSTRACT The increasing demand for bricks makes many alternatives to bricks is lightweight bricks. Lightweight bricks is an innovation form conventional bricks which has a lighter density. Lightweight bricks are made by inserting foam into cement mixture during the cement paste manufacturing process so that it has brighter than conventional brick therefore lighweight bricks are widely used…
